Yuanyanglong bainian Hao et al., 2024 (new genus and species)

(Partial skeletons of Yuanyanglong bainian, from Hao et al., 2024)

Meaning of name: Yuanyanglong = mandarin duck [a symbol of lifelong monogamy, referring to the fact that two individuals were preserved together] dragon [in Chinese]; bainian = one hundred years [in Chinese, commemorating the fact that Oviraptor and Chirostenotes, two of the first oviraptorosaurs to be scientifically described, were named 100 years ago in 1924]

Age: Early Cretaceous (Aptian–Albian)

Where found: Miaogou Formation, Inner Mongolia, China

How much is known: Partial skeletons of two individuals, together including a partial skull, parts of the limbs, and some vertebrae.

Notes: Yuanyanglong was an oviraptorosaur, a group of bird-like theropods with short and often toothless skulls. It had relatively long legs (and especially shins) for its size. Although long legs are often an adaptation for fast running, the pelvis of Yuanyanglong does not have much space for the attachment of muscles that pull the hindlimbs back, leading its describers to suggest that it may have used its long legs for wading through water instead.

Both known specimens of Yuanyanglong were preserved with clusters of pebbles in their body cavity (though in one specimen, these pebbles were accidentally removed during fossil preparation), indicating that it probably used gizzard stones to grind up its food. Gizzard stones have also been found in the slightly older oviraptorosaur Caudipteryx.

Yuanyanglong is estimated to have weighed around 12 kg, making it larger than earlier oviraptorosaurs such as Caudipteryx, but smaller than many Late Cretaceous oviraptorosaurs.

Iguanodon

(temporal range: 126-122 mio. years ago)

[text from the Wikipedia article, see also link above]

Iguanodon (/ɪˈɡwɑːnədɒn/ i-GWAH-nə-don; meaning 'iguana-tooth'), named in 1825, is a genus of iguanodontian dinosaur. While many species found worldwide have been classified in the genus Iguanodon, dating from the Late Jurassic to Early Cretaceous, taxonomic revision in the early 21st century has defined Iguanodon to be based on one well-substantiated species: I. bernissartensis, which lived during the Barremian to early Aptian ages of the Early Cretaceous in Belgium, Germany, England, and Spain, between about 126 and 122 million years ago. Iguanodon was a large, bulky herbivore, measuring up to 9–11 metres (30–36 ft) in length and 4.5 metric tons (5.0 short tons) in body mass. Distinctive features include large thumb spikes, which were possibly used for defense against predators, combined with long prehensile fifth fingers able to forage for food.

The genus was named in 1825 by English geologist Gideon Mantell but discovered by William Harding Bensted, based on fossil specimens found in England and was given the species name I. anglicus. Iguanodon was the second type of dinosaur formally named based on fossil specimens, after Megalosaurus. Together with Megalosaurus and Hylaeosaurus, it was one of the three genera originally used to define Dinosauria. The genus Iguanodon belongs to the larger group Iguanodontia, along with the duck-billed hadrosaurs. The taxonomy of this genus continues to be a topic of study as new species are named or long-standing ones reassigned to other genera. In 1878 new, far more complete remains of Iguanodon were discovered in Belgium and studied by Louis Dollo. These were given the new species I. bernissartensis. In the early 21st century it became understood that the remains referred to as Iguanodon in England belonged to four different species (including I. bernissartensis) that were not closely related to each other, which were subsequently split off into Mantellisaurus, Barilium and Hypselospinus. It was also found that the originally described type species of Iguanodon, I. anglicus was a nomen dubium, and not valid. Thus the name "Iguanodon" became fixed around the well known species based primarily on the Belgian specimens. In 2015, a second valid species, I. galvensis, was named, based on fossils found in the Iberian Peninsula.

Scientific understanding of Iguanodon has evolved over time as new information has been obtained from fossils. The numerous specimens of this genus, including nearly complete skeletons from two well-known bone beds, have allowed researchers to make informed hypotheses regarding many aspects of the living animal, including feeding, movement, and social behaviour. As one of the first scientifically well-known dinosaurs, Iguanodon has occupied a small but notable place in the public's perception of dinosaurs, its artistic representation changing significantly in response to new interpretations of its remains.

Daurlong vs Natovenator

Factfiles:

Daurlong wangi

Artwork by @i-draws-dinosaurs, written by @i-draws-dinosaurs

Meaning: Wang’s Daur dragon (named for the Daur people of Northeast China)

Time: 121 million years ago (Aptian stage of the Early Cretaceous)

Location: Longjiang Formation, Inner Mongolia, China

Daurlong was described in 2022, from a stunningly beautiful fossil that includes the entire body, crushed flat by pressure, and a whole lot of soft tissues like feathers along the back of the neck and even the shape of the intestines! Any part of the digestive system is extremely rare to find in fossils, so Daurlong provides an important glimpse into how the digestive systems of birdlike dinosaurs compare to living dinosaurs today!

Turns out, despite being closely related to the ancestors of modern birds Daurlong’s guts were pretty similar to other, much more distant theropods like Scipionyx instead. That helps fill in a pretty big gap in our knowledge of how the bird digestive system evolved, making this a very scientifically valuable fossil!

That, and it’s just adorable. Look at that lil smiley face!

Natovenator polydontus

Artwork by Yusik Choi, written by @zygodactylus

Name Meaning: Many toothed swimming hunter 

Time: 71 million years ago (Maastrichtian stage of the Late Cretaceous) 

Location: Hermiin Tsav, Barun Goyot Formation, Ömnögovi, Mongolia 

Back in my day, we famously said dinosaurs weren’t aquatic or volant, apart from birds that fit the bill. Fortunately, my childhood is over, and we have both flighted and aquatic nonavians - Natovenator being the next iteration in this strange new reality. Like its cousin Halszkaraptor, Natovenator was a semiaquatic raptor, adapted for moving through the water, potentially with wing flippers to do so. It had a long snout with many teeth adapted for grabbing aquatic life, and it had a long neck similar to modern day diving birds to help it catch prey. It had a streamlined body, allowing it to dive and move through the water efficiently. The long snout was not spatulate, but did curve upward a bit, giving it a vaguely-duck like appearance. The small pointed teeth would have been excellent for grabbing on to struggling fish. Living in the Barun Goyot, a desert ecosystem, Natovenator probably congregated around steady sources of water, such as periodic lakes and oases like those found in modern deserts today. Many mammals are known from the ecosystem, but the real standout stars are dinosaurs: Natoveantor shared its habitat with Ceratonykus, Saichania, Tarchia, Zaraapelta, Gobipipus, Gobipteryx, Hollanda, Bagaceratops, other dromaeosaurs, Conchoraptor, Heyuannia, and unnamed sauropods known only from eggs. Appearing after the Djadokhta and preceding the Nemegt, this environment was a transitional one from the Campanian of Asia to the Maastrichtian, as the environment became more diverse and filled with truly insane numbers of dinosaurs as the period reached its end.

[reneg661]

Is a genus of herbivorous basal hadrosauriform dinosaur that lived during the Aptian stage of the Early Cretaceous of modern-day Niger and Cameroon. Ouranosaurus measured about 7 to 8.3 metres (23 to 27 ft) long. Two rather complete fossils were found in the Elrhaz Formation, Gadoufaoua deposits, Agadez, Niger, in 1965 and 1970, with a third indeterminate specimen known from the Koum Formation of Cameroon. The animal was named in 1976 by French paleontologist Philippe Taquet; the type species being Ouranosaurus nigeriensis. The name is a combination of the Arabic word for "courage" and the country of discovery, although ourane is also the Tuareg name for the desert monitor.

[albertonykus]

Is there any evidence that can explain why the Stegosaurs began declining after the Jurassic & eventually became extinct by the mid/late-ish Cretaceous? Could competition from their Thyreophoran relatives, the Ankylosaurs, possibly have been a contributing factor? What was the last Stegosaur?

It has been observed that the decline of stegosaurs appears to have coincided with the decline of cycads, so it’s possible that the two were linked in some way, but teasing out the nature of long-term ecological interactions from the fossil record is pretty difficult. The youngest known uncontroversial stegosaur is probably Mongolostegus from the Aptian–Albian of Mongolia, though there are reportedly undescribed Coniacian stegosaur remains known from India and possible stegosaur-like tracks as young as the Maastrichtian.

Acrocanthosaurus

Acrocanthosaurus atokensis [ak-ro-KAN-tho-SAWR-us] [AT-oh-KEN-zis]

“High-spined Lizard”

Acrocanthosaurus lived in what is now North America during the Aptian and Albian stages of the Early Cretaceous. It’s fossil remains are found mainly in Oklahoma, Texas, and Wyoming, although teeth have been found as far as Maryland.

Acrocanthosaurus was among the largest known theropods known to exist, being related to Carcharodontosaurus and Giganotosaurus. The largest known specimen estimated to have been 11.5 meters (38 feet) from nose to tail and weighed 5.7 to 6.2 metric tons.

Acrocanthosaurus was a theropod dinosaur or a bipedal apex predator. It is best known for its high neural spines on its vertebrae. This ridge most likely served as an anchor point for large muscles on its neck and back, although it is often represented as a narrow and colourful sail.

Acrocanthosaurus was the largest theropod in its ecosystem and preyed on sauropods, ornithopods, and ankylosaurids. It had a strong neck and moderately sized arms with three hooked claws on each. Its skull was 1.3 meters (4.3 feet) in length and was long and narrow like most allosauroids.

Acrocanthosaurus is one of my favourite dinosaurs, if not my most. I love this thing and wish it was more popular and well known. I personally prefer giving it a more defined and narrow sail as opposed to a smaller fatter hump, as I feel it makes it appear more distinct compared to a Giga or Charchar. I also, as I do with most of my theropods, give it a small vague amount of fluff or fur-like fuzz on its body, as you can see on its elbows, where it doesn’t really start or end. That’s not meant to imply its completely covered in fur, just that it has some fuff, and is covered in hide rather than scales.

Kiyacursor longipes Averianov et al., 2024 (new genus and species)

(Type specimen of Kiyacursor longipes, from Averianov et al., 2024)

Meaning of name: Kiyacursor = Kiya River runner [in Latin]; longipes = long foot [in Latin]

Age: Early Cretaceous (Aptian)

Where found: Ilek Formation, Kemerovo Oblast, Russia

How much is known: Partial skeleton of one individual including several vertebrae and limb bones. A partial neck vertebra found at the same site may belong to the same individual.

Notes: Kiyacursor was a ceratosaurian theropod. It resembles the Late Jurassic ceratosaurs Elaphrosaurus of Tanzania and Limusaurus of China in having relatively elongate lower legs and feet, suggesting that it was well adapted for fast running. The type specimen of Kiyacursor is estimated to have been 2.5 m long in total body length, but it probably had not finished growing when it died.

Although ceratosaurs are known from the Late Cretaceous of Europe and especially the Southern Hemisphere, Kiyacursor is the youngest known ceratosaur from Asia. In addition to Kiyacursor, the Ilek Formation has produced fossils of various other animals that are more characteristic of Jurassic ecosystems, including certain types of proto-salamanders, proto-crocodylians, and proto-mammals. This may indicate that what is now Western Siberia acted as a "lost world" for some Jurassic animal groups during the Early Cretaceous.

Scientists have discovered essentially the most elaborately dressed-to-impress dinosaur ever described and say it sheds new gentle on how birds comparable to peacocks inherited their capacity to point out off.

The brand new species, Ubirajara jubatus, was chicken-sized with a mane of lengthy fur down its again and stiff ribbons projecting out and again from its shoulders, options by no means earlier than seen within the fossil file.

It’s thought its flamboyant options have been used to dazzle mates or intimidate foe.

A global staff of scientists co-led by Professor David Martill and researcher Robert Smyth, each on the College of Portsmouth, and Professor Dino Frey on the State Museum of Pure Historical past, Karlsruhe, Germany found the brand new species whereas analyzing fossils in Karlsruhe´s assortment.

The research is printed within the scientific journal Cretaceous Analysis.

Professor Martill mentioned: “What is particularly uncommon concerning the beast is the presence of two very lengthy, in all probability stiff ribbons on both facet of its shoulders that have been in all probability used for show, for mate attraction, inter-male rivalry or to frighten off foe.

“We can’t show that the specimen is a male, however given the disparity between female and male birds, it seems possible the specimen was a male, and younger, too, which is stunning given most advanced show talents are reserved for mature grownup males.

“Given its flamboyance, we will think about that the dinosaur might have indulged in elaborate dancing to point out off its show buildings.”

The ribbons will not be scales or fur, nor are they feathers within the trendy sense. They seem like buildings distinctive to this animal.

Mr Smyth mentioned: “These are such extravagant options for such a small animal and in no way what we might predict if we solely had the skeleton preserved. Why adorn your self in a approach that makes you extra apparent to each your prey and to potential predators?

“The reality is that for a lot of animals, evolutionary success is about extra than simply surviving, you additionally should look good if you wish to go your genes on to the following era.

“Trendy birds are famed for his or her elaborate plumage and shows which might be used to draw mates – the peacock’s tail and male birds-of-paradise are textbook examples of this. Ubirajara exhibits us that this tendency to point out off just isn’t a uniquely avian attribute, however one thing that birds inherited from their dinosaur ancestors.”

Ubirajara jubatus lived about 110 million years in the past, throughout the Aptian stage of the Cretaceous interval, and is carefully associated to the European Jurassic dinosaur Compsognathus.

A piece of the lengthy, thick mane operating down the animal´s again is preserved almost intact. The arms have been additionally coated in fur-like filaments all the way down to the arms.

The mane is believed to have been managed by muscle tissues permitting it to be raised, in the same approach a canine raises its hackles or a porcupine raises its spines when threatened.

Ubirajara might decrease its mane near the pores and skin when not in a show mode permitting the creature to maneuver quick with out getting tangled in vegetation.

Professor Martill mentioned: “Any creature with movable hair or feathers as a physique protection has a terrific benefit in streamlining the physique contour for sooner hunts or escapes but additionally to seize or launch warmth.”

The mane is not the one extraordinary characteristic.

The researchers describe as ‘enigmatic’ the creature’s lengthy, flat, stiff shoulder ribbons of keratin, every with a small sharp ridge operating alongside the center. These ribbons have been positioned to not impede freedom of motion in its legs and arms, so would not have restricted the animal’s capacity to hunt, preen and ship indicators.

Mr Smyth argues the flowery plumage of Ubirajara might need improved its probabilities of survival.

He mentioned: “We all know plenty of dinosaurs had bony crests, spines and frills that have been in all probability used for show however we do not see these fairly often in residing birds. In birds, crests are fabricated from feathers.

“This little dinosaur supplies some perception into why this is perhaps the case.

“Bone requires quite a lot of vitality for a physique to develop and preserve, it is also heavy and might trigger critical damage if damaged.

“Keratin – the fabric that makes up hair, feathers and scales – is a a lot better show different for a small animal like this one. Keratin is less expensive for a physique to provide, it is also light-weight, versatile and may be frequently changed if broken.

“Ubirajara is essentially the most primitive identified dinosaur to own integumentary show buildings. It represents a revolution in dinosaur communication, the results of which we will nonetheless see immediately in residing birds.”

Professor Frey excavated the specimen from the 2 slabs of stone through which it lay and, utilizing x-ray, discovered beforehand hidden skeletal components and tender tissue, permitting the researchers to construct a transparent image of its options.

Ubirajara jubatus is the primary non-avian dinosaur to be described from Brazil’s Crato Formation, a shallow inland sea laid down about 110 million years in the past. It’s also the primary non-avian dinosaur discovered on the traditional supercontinent of Gondwana with preserved pores and skin.

One other of the researchers on the staff, Hector Rivera Sylva, from Museo del Desierto, Mexico, mentioned in addition to the invention being a watershed on this subject, it was additionally essential for the Americas.

He mentioned: “The Ubirajara jubatus just isn’t solely essential due to the integumentary buildings current for the primary time in a non-avian dinosaur, utterly altering the way in which of seeing the behaviour of sure dinosaurs. Slightly, the scientific worth transcends, forming a watershed, since it’s the first proof for this group in Latin America, in addition to one of many few reported for the subcontinent of Gondwana, increasing the information about non-avian feathered dinosaurs for America, whose proof could be very scarce.”

4" Genuine Spinosaurus Dinosaur Tooth Fossil, Kem Kem Beds, Cretaceous Morocco | Authentic Specimen + COA

4" Genuine Spinosaurus Dinosaur Tooth Fossil – Kem Kem Beds, Tegana Formation, Aptian Stage, Cretaceous: Kem Kem Basin, Morocco

A rare and impressive piece of prehistoric life — this 4-inch fossil tooth belonged to the legendary Spinosaurus aegyptiacus, one of the largest and most unusual carnivorous dinosaurs. Collected from the world-renowned Kem Kem Beds within the Tegana Formation of the Kem Kem Basin, southeastern Morocco, this tooth dates to the Aptian stage of the Early Cretaceous, approximately 113 to 100 million years ago.

Fossil Type & Species:

Type: Vertebrate Fossil (Tooth – crown specimen)

Species: Spinosaurus aegyptiacus

Order: Theropoda

Superfamily: Megalosauroidea

Family: Spinosauridae

Described by: German palaeontologist Ernst Stromer in 1915

Geological Details:

Formation: Tegana Formation

Beds: Kem Kem Beds

Geological Stage: Aptian (Early Cretaceous)

Age: ~113–100 million years ago

Zone/Biozone: Kem Kem Compound Assemblage Zone

Depositional Environment: Ancient fluvial and deltaic systems; river channels, floodplains, and shallow lakes where a mix of aquatic and terrestrial life flourished

Morphology & Features: This Spinosaurus tooth displays several key features:

Conical shape with a slightly flattened profile

Non-serrated enamel – ideal for gripping fish and aquatic prey

Fine longitudinal ridges along the surface of the tooth

Robust crown preservation with no major restorations

Fossilised hues in deep reds, ochres, and browns from natural mineralisation

Notable: With a body possibly exceeding 15 metres in length, Spinosaurus aegyptiacus is believed to be the only dinosaur adapted for a semi-aquatic lifestyle. It had a crocodile-like skull and used its long teeth to hunt fish and other aquatic creatures. Fossils from the Kem Kem Beds offer rare insights into this iconic predator, and a 4-inch tooth is a substantial and display-worthy specimen.
