Coming right around the Chinese New Year, top to bottom, are two highly scientifically-important dinosaurs hailing from the Aptian-aged (125-118 mya) Jiufotang Formation of China’s Liaoning Province:

Microraptor zhaoianus ranks alongside the late Jurassic Archaeopteryx and the closely-related Sinornithosaurus as one of the first theropod dinosaurs ever to have discovered with full feather and wing impressions. It measured about 80 cm (2.6ft) in length, had a wingspan of 99 cm (3.25 ft) and weighed about 1.25-1.88 kg, sported a uniquely black but iridescent plumage, and is the namesake of the Microraptoridae, a family of raven-sized dromaeosaurs that dominated the Jehol Biota of the Jiufotang and Yixian Formations and are particularly famous for sporting long flight feathers on both their legs and limbs. This “four-winged” configuration, which surprisingly resembles the hypothetical “Tetrapteryx” stage of bird evolution proposed by naturalist William Beebe in 1915, enabled Microraptor and its kin to glide from tree to tree in pursuit of small birds, lizards and mammals as well as achieving some sort of powered flight over short distances.

Psittacosaurus is a basal ceratopsian that is closer in phylogeny to creatures like Styracosaurus and Triceratops than to the more primitive Yinlong from the late Jurassic, and is one of the most well-preserved and best-studied genera of all non-avian dinosaurs. It reached the size of a pig or a retriever dog and lived throughout much of continental Eastern Asia 125-105 million years ago, and is known for having the most species described of any non-avian dinosaur, with 12 different species ranging from as far north as Siberia to as far south as Thailand. Two of these species were both found in the Jiufotang Formation - P.melieyingensis and P.mongoliensis, the type species which measured up to 2 meters (6.2 ft) long and weighed about 80 kg (44 lb). Psittacosaurus had highly-developed senses of smell and vision, a pair of protruding jugal (cheek) bones that were possibly used for display, and was active for short periods at day or night. Psittacosaurus also possessed self-sharpening teeth that were used for cropping and slicing tough plants, and unlike future ceratopsians, it lacked teeth for chewing and grinding food and thus used gastroliths (which would have been stored in a gizzard similar to those of modern birds) to wear down the leaves and bark that it ate as it passed through the digestive system. Psittacosaurus is also unique among ceratopsians for having a large, well-proportioned brain. This indicates that the dinosaur was capable of doing a wide range of complex social behaviors such as bird-like sleeping, nest-building and parental care. This is perhaps true with possible instances of overburdened Psittacosaurus parents brining in a nanny or another guardian to take care of large nests of more than a dozen hatchlings, as evidenced of fossils of adolescent females preserved with several hatchlings together. The Psittacosaurus of the Jiufotang Formation shared their temperate forest habitat with the basal ankylosaur Chuanqilong, several genera and species of paravians and pterosaurs, a large titanosaur, and the 10-meter-long Yutyrannus relative Sinotyrannus, and Psittacosaur hatchlings and occasionally adults were also preyed upon by the large, badger-like mammal Repenomamus. One fossil Psittacosaurus specimen that is on display at a German museum (SMF R 4970) preserves the scales, colors and integument that the living animal would have had, and they indicate that the particular Psittacosaurus had a counter-shaded reddish brown and beige pattern that was blurrier and less-defined compared to the striking orange-and-white colors of Sinosauropteryx (which was suited for a lifestyle of foraging in open areas) and was therefore useful for camouflaging the Psittacosaurus in the woods. The specimen also possessed a strange crest of yellow, keratinized, bristle-like structures protruding from the base of its tail that were quite similar to the thin, filamentous structures found on the heterodontosaurid Tianyulong, which also possibly indicates that feather-like structures or proto-feathers may have appeared early in the evolutionary history of the dinosaurs and were soon lost in the evolution of some dinosaur groups or retained in some form in the evolution of others.

Round Four: Berthasaura vs Caihong

Berthasaura leopoldinae

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

Name meaning: Bertha and Leopoldina’s reptile (in honour of naturalist and women’s rights activist Bertha Maria Júlia Lutz, and first Empress of Brazil and advocate for Brazilian independence Maria Leopoldina)

Time: Uncertain, likely ~121 to 75 million years ago (Aptian to Albian stages of the Early Creataceous) but may be younger

Location: Goio-Erê Formation, Brazil

Theropods are famously carnivorous dinosaurs, but many, many groups of theropods have decided “actually but what if I didn’t” and gone vegetarian, and yet it’s still wild when another one of those pops up every now and then. Even among them though, Berthasaura is special for being the only theropod that seems to have tried to just straight up turn itself into an ornithopod. The long spindly legs, the teeny little arms, and a big head with a toothless beak all come together to create an utterly bizarre little theropod that honestly nobody could have predicted.

Berthasaura is a noasaur, and those of you familiar will at this moment be saying “oh of course it’s a noasaur” because those guys were small ceratosaurs that were basically Theropod Wacky Experimental Phase 1.0. Within this group you’ve got wild sticky-outy teeth, a single weight-bearing toe on each foot in our fellow competitor Vespersaurus, and now multiple instances of beaks evolving independently. Theropods just love to evolve a beak, what can I say? Whatever the hell Berthasaura had going on, it must have been successful because as the basalmost noasaurid currently known its direct lineage has been surviving since at least the Late Jurassic!

Caihong juji

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

Name meaning: Rainbow with big crest

Time: 161 million years old (Oxfordian stage of the Late Jurassic)

Location: Tiaojishan Formation, China

It’s always a special treat to hear the announcement of a dinosaur with known colours, because it gives the most direct impression of how truly stunning these animals would have been to witness in real life. And Caihong might just be the most spectacular of them all so far, described in 2018 from an immaculate full-body fossil that preserves detailed feathers! Caihong’s feathers are longer than some other floofy dinosaurs, and would have had the appearance of a luxurious mane along its neck. Not only that, the fossil preserves feather microstructures that in life would have made this dinosaur gloriously iridescent!

Now iridescent dinosaurs aren’t new, Microraptor has been decked out in fabulous starling-esque plumage for a while now, but Caihong absolutely takes it to the next level. Its whole body was covered in iridescent black, including the enormous tail, but the real star of the show are the platelet-like melanosomes found on the head, neck, and the base of the tail. Different from the usual iridescent melanosomes, the structure of these tiny organelles reflects brilliantly iridescent colours, like those on the heads of hummingbirds and particularly the bright purple feathers on the necks of the trumpeter family. Caihong would have put on an absolutely dazzling jewel-toned display in the treetops or on the forest floor of prehistoric China!

Berthasaura leopoldinae de Souza et al., 2021 (new genus and species)

(Select bones and schematic skeletal of Berthasaura leopoldinae, with preserved bones in white, from de Souza et al., 2021)

Meaning of name: Berthasaura = [Brazilian zoologist and politician who was a leading figure during the Pan American feminist movement] Bertha Maria Júlia Lutz’s lizard; leopoldinae = for Maria Leopoldina [the first Empress of Brazil] and Imperatriz Leopoldinense [a samba school that developed a theme to commemorate the National Museum of Brazil]

Age: Early Cretaceous (Aptian–Albian)

Where found: Goio Erê Formation, Paraná, Brazil

How much is known: Nearly complete skeleton of one individual.

Notes: Berthasaura was a small ceratosaurian theropod, less than a meter long in total body length. To be fair, the only known specimen was probably not fully grown. Based on comparison to other ceratosaurs with more completely known growth series, however, it was likely not an early juvenile individual either.

Whereas most other ceratosaurs were sharp-toothed predators, Berthasaura was extremely unusual in having toothless jaws, and it may have instead been an herbivore or an omnivore. The only other toothless ceratosaur named previously was Limusaurus from the Late Jurassic of China. Interestingly, the describers of Berthasaura found that it was probably not especially closely related to Limusaurus. If this is correct, ceratosaurs evolved into toothless forms at least two separate times in their evolutionary history.

Although Limusaurus was a toothless herbivore as an adult, it had sharp teeth as a juvenile. If Berthasaura also went through this process, it might have lost its teeth at an earlier growth stage than Limusaurus did, given the immaturity of the type specimen. However, it is also possible that it was toothless throughout its life. Without additional fossils of Berthasaura at other growth stages, it is hard to be sure.

[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.

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.

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.”
