Bannykus vs Ambopteryx

Factfiles:

Bannykus wulatensis

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

Name meaning: Half claw from Wulatehouqi

Time: 113 to 100 million years ago (Albian stage of the Early Cretaceous)

Location: Bayin-Gobi Formation, Inner Mongolia, China

If there’s one group of dinosaurs that has most recently gained more fame among casual dinosaur fans it’s probably alvarezsauridae, elevated to stardom by the Mononykus that captured everyone’s hearts in Prehistoric Planet. The bizarre group of single-clawed maniraptorans has been studied for a while, but their evolutionary origins have fairly mysterious until recently. How did that whole giant thumb claw thing happen??

Published in 2018 alongside more basal alvarezsaur Xiyunykus, Bannykus helps to fill in a gap in that evolutionary pathway! More specifically, they help to fill in a 70 million year long gap between the primitive Late Jurassic Haplocheirus and the very end of the Cretaceous! Notably, Bannykus has a larger thumb claw that the rest of its claws, but the other fingers are at least partially functional instead of just nubbins. It’s a lot easier to see how the later alvarezsaurids got to where they are from here! Next time you lose your mind over the Mononykus from Prehistoric Planet (which I do at least weekly), say a thank you to the lil guy with slightly less weird hands. Thumbs up to Bannykus!

Ambopteryx longibrachium

Name meaning: Both wings with long arms

Time: 163 million years ago (Callovian stage of the Middle Jurassic)

Location: Haifanggou Formation, China

Look, evolution has done a lot of weird stuff to dinosaurs. It put penguins underwater, and did whatever the hall mamenchisaurid necks are, and game lambeosaurs a built-in face trumpet. But I would argue there is one group that represents dinosaur evolution at its most unhinged, and that is scansoropterygidae.

Scansoriopterygids were generally considered “weird little tree dinosaurs” in the 2000s, with long fingers to pick grubs out of bark or something. Then Yi qi swept along in 2015 and revealed that those long fingers were actually supporting membranous bat wings. With an extra bony rod (the “styliform element”) sticking out of the wrist to help support it, because well if you’re a dinosaur evolving bat wings why bother being normal about it after that? Although really, the dinosaurs did it first so bats actually have dinosaur wings.

Yi was sensational, but it was also extremely weird and completely unique. Even other scansoriopterygids didn’t have wing membranes, so the whole bat thing was a bit up in the air. Or not up in the air, as the case may be. But then along comes Ambopteryx, published in 2019, packing another set of skin wings, and the vindication of Yi is complete! 

Ambopteryx preserves a styliform element and wing membrane, as well as a thick coat of feathers, and honestly out of a whole selection of dinosaurs I think these might be some of the most huggable in the lot. Obviously this whole wing membrane thing didn’t end up working out for them long term, but Ambopteryx is part of an incredible lineage that challenged what we thought was possible for dinosaurs!

A selection of new dinosaurs named in 2018.

Evolution of alvarezsaur represented by three species; Xiyunykus, Bannykus and Shuvuuia.

[mindblowingscience]

Two newly discovered dinosaurs may be missing links in an unusual lineage of predators that lived between 160 million and 90 million years ago, new research suggests.

The two species, Xiyunykus and Bannykus, were theropods—a group of bipedal, largely carnivorous dinosaurs. Some theropods eventually gave rise to birds, while another branch, the alvarezsauroids, evolved into strange-looking insectivores with short arms and hands with an enlarged finger for digging into nests.

But until now, little was understood about how this change happened because of the 70-million-year evolutionary gap separating the insect-eating alvarezsauroids from the earliest known member of the group, Haplocheirus.

"The significance of Xiyunykus and Bannykus is that they fall within that gap and shed light on patterns of evolution within Alvarezsauroidea," explained Corwin Sullivan, a University of Alberta paleontologist who participated in the international study.

Discovery of two new Chinese dinosaurs An international research team today announces the discovery of two new Chinese dinosaurs -- Bannykus and Xiyunykus; Prof. Jonah Choiniere of Wits University co-authored the research Professor Jonah Choiniere from the University of the Witwatersrand, Johannesburg, South Africa was a leading member of the team and is a co-author on the research. The dinosaurs are both alvarezsaurs, an enigmatic group of theropod [meat-eating] dinosaurs, which have many similarities with birds and which show adaptations thought to be related to eating insects that live in colonies. "Alvarezsaurs are weird animals," said Choiniere. "With their strong, clawed hands and weak jaws, they appear to be the dinosaurian analogue to today's aardvarks and anteaters." But alvarezsaurs did not originally eat insects. The earliest members of the group had more typically meat-eating teeth and hands, useful for catching small prey. Only later-evolving members reduced their teeth and evolved a hand with a huge, single claw capable - perhaps - of tearing open rotting logs and anthills. "The new fossils have long arms, and so show that alvarezsaurs evolved short arms only later in their evolutionary history, in species with small body sizes. This is quite different to what happens in the classic example of tyrannosaurs, which have short arms and giant size," said co-author Professor Roger Benson of Oxford University. Bannykus and Xiyunykus are important because they show transitional steps in the process of alvarezsaurs adapting to new diets. "The fossil record is the best source of information about how anatomical features evolve," said James Clark, co-author and an Honorary Professor at Wits University. "And like other classic examples of evolution such as the 'horse series', these dinosaurs show us how a lineage can make a major shift in its ecology over time." The specimens were discovered during collaborative international fieldwork in China. Xiyunykus was discovered in 2005 in Xinjiang, north-western China. Bannykus was discovered a few years later, in 2009, in Inner Mongolia, north-central China. Both research trips were joint expeditions co-led by Professors Xu Xing (Institute for Vertebrate Palaeontology and Palaeoanthropology, Beijing) and James Clark (George Washington University, Washington DC). "Our international field teams have been tremendously productive over the years," said Xing. "And this research showcases just some of our incredible discoveries." Once the fossils were discovered, their further study was made possible by a joint South Africa/China collaborative grant through South Africa's National Research Foundation, held by Choiniere and Xu. "The joint research programme has helped in so many ways," said Choiniere. "China and South Africa have a great deal of overlap in palaeontology, and it has been a privilege to cross-train students over the last two years."

An article published in the journal "Current Biology" describes the discovery of two species of dinosaurs belonging to the Alvarezsauria group, which shares many characteristics with modern birds, in north-western China. A team of researchers studied the fossils of the species that were named Xiyunykus pengi and Bannykus wulatensis recognizing some characteristics intermediate between the oldest species of that group and others that lived several million years later, showing for example how the morphology of their arms evolved slowly.

Researchers Discover Two New Chinese Dinosaurs: Bannykus computer   and Xiyunykus

Digit reduction occurs many times in tetrapod evolution, and the most famous example is the ‘horse series’ of North America. An international research team announced the discovery of two new Chinese dinosaurs: Bannykus and Xiyunykus, in the journal Current Biology, which shed light on how alvarezsaurian dinosaurs reduced and lost their fingers.

The new dinosaurs are based on two fossils collected by a joint research team led by XU Xing from the Institute of Vertebrate Palaeontology and Palaeoanthropology (IVPP) of the Chinese Academy of Sciences. Xiynykus was discovered in 2005 in Zhunggar Basin, northwestern China, and Bannykus was discovered a few years later in 2009 in western Inner Mongolia, north-central China.

The new Alvarezsaurian dinosaurs are among the most bizarre groups of theropods, with extremely short, robust forelimbs with a single functional claw and gracile, bird-like skulls and hindlimbs. These specializations have led to controversy about their phylogenetic placement, biogeographic history, and ecological role in Mesozoic ecosystems.

AT early times, unspecialized alvarezsaur fossils were the key to resolving this controversy, but until recently the group had at least a 90 million year gap in its fossil record, especially during the Early Cretaceous.

The new dinosaurs fall nearly at the midpoint of the 90-million year temporal gap between the earliest and latest alvarezsaurs. They contribute key phylogenetic and biogeographic information that firmly resolves Alvarezsauria as a monophyletic clade originating in Asia and dispersing to other continents.

The new findings show that clear anatomical specializations also present in later members of the clade, such as a hypertrophied first digit, mechanically efficient forearm, and robust humerus. However, they preserve plesiomorphic forelimb proportions not present in later-branching members.

Together, these observations document a major macroevolutionary shift from the plesiomorphic theropod condition of a relatively long arm and grasping hand in the earliest alvarezsaurs (e.g., Haplocheirus), to a long arm with a specialized hand in Bannykus and Xiyunykus, to the highly specialized short-l Vending Computer  imbed, functionally monodactyl hand in the latest evolving members of the clade. “This transition plays out in an incremental fashion over more than 50 million years,” said XU, “it could one day potentially serve as a classic example of macroevolution akin to the ‘horse series’ of North America.” “Alvarezsaurs are weird animals,” said Dr. Jonah Choiniere from the University of the Witwatersrand of South Africa, a co-author of the report, “with their strong, clawed hands and weak jaws, they appear to be the dinosaurian analogue to today’s aardvarks and anteaters.”

But the earliest alvarezsaurs had more typical, meat-eating teeth and hands useful for catching small prey, and only later-evolving alvarezsaurs evolved a hand with a huge, single claw capable perhaps of tearing open rotting logs and anthills. Bannykus and Xiyunykus are important because they show transitional steps in the process of alvarezsaurs adapting to new diets. “The fossil record is the best source of information about how anatomical features evolve,” said James Clark from George Washington University, “and like other classic examples of evolcashless vendingution such as the ‘horse series,’ these dinosaur Overhead Line Monitoring  s show us how a lineage can make a major shift in its ecology over time.”

Dr. Roger Benson from the University of Oxford said, “The new fossils have long arms, showing that alvarezsaurs evolved short arms only later in their evolutionary history, in species with small body sizes. This is quite different to what happens in the classic example of tyrannosaurs, which have short arms and giant size.”

The earliest drawing in history: A hashtag found in South Africa

A 73,000-12 months-old crimson cross-hatch sample was drawn on a flake of silicrete, which kinds when sand and gravel cement alongside one another, and identified in a cave in South Africa.

A suite of Center Neolithic pottery such as normal Danilo ware, figulina and rhyta that was made use of to keep meat, milk, cheese and yogurt.

These four dinosaurs showcase the evolution of alvarezsaurs. From still left, Haplocheirus, Xiyunykus, Bannykus and Shuvuuia expose the lengthening of the jaws, reduction of teeth and changes in the hand and arm.

Eorhynchochelys sinensis is an early turtle that lived 228 million years ago. It experienced a toothless beak, but no shell.

The leg bones of a 7-12 months-old, recovered from an historical Roman cemetery, present bending and deformities linked with rickets.

The famed Easter Island statues, called moai, ended up originally total-human body figures that have been partly covered about the passage of time. They signify significant Rapa Nui ancestors and were carved after a population was founded on the island 900 a long time back.

Scientists stand at the excavation website of Aubrey Gap 7, in which cremated human continues to be were being recovered at Stonehenge to be researched. New exploration suggests that 40% of 25 individuals buried at Stonehenge were not from there — but they probably transported stones from west Wales and served establish it.

The fossil of the freshly found out armored dinosaur Akainacephalus johnsoni was observed in southern Utah.

The foot is 1 element of a partial skeleton of a 3.32 million-yr-old skeleton of an Australopithecus afarensis youngster dubbed Selam.

The asteroid impact that brought on dinosaurs to go extinct also destroyed international forests, according to a new examine. This illustration shows just one of the handful of floor-dwelling birds that survived the toxic atmosphere and mass extinction.

The remains of a butchered rhinoceros are encouraging researchers to day when early human beings achieved the Philippines. They observed a 75% total skeleton of a rhinoceros that was evidently butchered, with 13 of its bones exhibiting cut marks and parts the place bone was struck to launch marrow, at the Kalinga archaeological web page on the island of Luzon.

This is just a person of 26 individuals uncovered at the website of a fifth-century massacre on the Swedish island of Öland. This adolescent was found lying on his side, which indicates a slower loss of life. Other skeletons observed in the homes and streets of the ringfort at Sandby borg present indications of unexpected death by blows to the head.

The skeleton of a younger female and her fetus had been identified in a brick coffin dated to medieval Italy. Her skull shows an example of neurosurgery, and her baby was extruded immediately after loss of life in a unusual “coffin beginning.”

This part of a whale skull was uncovered at the Calaveras Dam building website in California, together with at minimum 19 others. Some of the pieces evaluate 3 ft very long.

A Stone Age cow cranium shows trepanation, a gap in the cranium that was developed by human beings as as surgical intervention or experiment.

On the still left is a fossilized cranium of our hominin ancestor Homo heidelbergensis, who lived 200,000 to 600,000 years ago. On the ideal is a present day human skull. Hominins experienced pronounced brow ridges, but modern-day humans advanced mobile eyebrows as their experience shape turned lesser.

On the left is a 13,000-year-old footprint as uncovered in the sediment on Calvert Island, off the Canadian Pacific coastline. On the right is a digitally enhanced picture, exhibiting facts of the footprint.

A central platform at Star Carr in North Yorkshire, England, was excavated by a investigation staff finding out past climate change activities at the Middle Stone Age site. The Star Carr web page is dwelling to the oldest proof of carpentry in Europe and of designed structures in Britain.

Scientists have been researching Archaeopteryx fossils for 150 several years, but new X-ray details expose that the fowl-like dinosaur may perhaps have been an “lively flyer.”

This wall with paintings is in the La Pasiega Cave in Spain. The ladder form of pink horizontal and vertical traces is far more than 64,000 decades outdated and was made by Neanderthals.

These perforated shells ended up uncovered in Spain’s Cueva de los Aviones sea cave and day to in between 115,000 and 120,000 several years back. Researchers believe that these served as physique ornamentation for Neanderthals.

The earliest fashionable human fossil at any time discovered outside the house of Africa has been recovered in Israel. This implies that fashionable individuals still left Africa at the very least 50,000 a long time previously than earlier considered. The upper jawbone, such as a number of teeth, was recovered in a prehistoric cave web-site.

This is an excavated composition at the northern edge of the Grand Plaza at Teposcolula-Yucundaa in Oaxaca, Mexico. Researchers investigated a “pestilence” cemetery connected with a devastating 1545-1550 epidemic. New analysis implies that salmonella triggered a typhoid fever epidemic.

Standing about 4 toes tall, early human ancestor Paranthropus boisei had a small mind and a extensive, dish-like deal with. It is most perfectly-identified for obtaining large teeth and hefty chewing muscle tissues.

#CBC: “Dinosaur discovery helps fill 70-million-year evolutionary gap”

[ad_1]

With the discovery of two dinosaur fossils in China, scientists think they have found the 70-million-year “missing link” between markedly different dinosaurs from the late Jurassic and the upper Cretaceous periods. 

The two species, called Bannykus and Xiyunykus, were members of the alvarezsaurid group of dinosaurs, insectivores that had short arms and small hands with one enlarged…
