Dinvember day 27: Beipiaosaurus (and a tiny Graciliraptor!)

The beast was apparently brown, but since only melanin cristals have been recovered from fossils, what's telling us Beipiaosaurus inexpectatus wasn't olive green?

Also I had to completely redo the neck because I we have recovered feathers there and I gave a bare neck (I had read the neck part litteraly 10 minutes before drawing):

Day 8: Graciliraptor lujiatunensis

yeah, I'm running a few days behind at this point due to irl issues. that said, I was looking forward to drawing this little fellow

Trivial

Graciliraptor requested by Kiyi on discord. It was kind of hard to get the sizing correct. But I tried my best. Plus, this profile doesn't exactly show off the slim dinosaur. But it's just a pose I didn't see floating around, and I figured I would do it. But here it is in all its glory.

Fun fact, This was going to be called starlight Hunt. As the raptor started looking like moon halfway through to me. But I decided to go with the original title of Trivial.

Round One: Sanxiasaurus vs Changmiania

Factfiles:

Sanxiasaurus modaoxiensis

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

Meaning: Sanxia lizard (after the Three Gorges of the Yangtze River) from Modaoxi (first tributary of the Yangtze)

Time: 170 million years (possibly Aalenian stage of the Middle Jurassic)

Location: Xintiangou Formation, Chongqing, China

Sanxiasaurus is a little ornithischian dinosaur named in 2019. Specifically, it’s a basal neornithischian, a group whose name has been known to induce spontaneous headaches among palaeontologists. Neornithischia is the group that includes ceratopsians, hadrosaurs, and many earlier forms, but the base of the group contains a whole truckload of little scampery bipedal critters who have proven very difficult to organise into a stable family tree. Sanxiasaurus seems to be one of the most basal of the group, and is actually the oldest ornithischian currently known from Asia! Living in the Xintiangou Formation, Sanxiasaurus shared its environment with lungfish, ray finned fish, sharks, temnospondyls, saruopterygians, crocodyliformes, turtles, and the theropod Yunyangosaurus, which was probably its main predator.

Changmiania liaoningensis

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

Name Meaning: Eternal Sleeper from Liaoning

Time: 125.755 million years ago (Barremian stage of the Early Cretaceous) 

Location: Lujiatun Beds, Yixian Formation, Liaoning, China 

Changmiania is a gorgeously preserved ornithopod known from the earliest time of the famed Yixian Formation, adding it to the ranks of amazing fossils known from this unique preservational environment. The multiple specimens of this species are found in sleeping poses, curled up on the ground with their legs and arms tucked up against them. This indicates they had been buried alive, possibly inside their own burrows. Given the depositional environment of Yixian is a sort of prehistoric Pompeii, with many dinosaurs covered very quickly in ash and dust from an exploding volcano, this makes a certain degree of sense - perhaps the two little dinosaurs had scurried into their burrow to escape the oncoming tragedy (sorry if I just made you sad), or had been asleep and unaware of the oncoming danger. At only one meter long and less than half a meter tall, Changmiania would have been easily missed in its environment, hiding among the dense vegetation from potential predators. With robust leg bones, it would have been a fast runner, able to move efficiently through the crowded undergrowth. It had a weirdly short neck for ornithischians, and that combined with its short forearms and hands indicates it was fossorial - ie, a digging animal, hence its burrow home and final resting place. Given they were found together, they were probably social creatures as well, living in small family groups. The Yixian was a dense temperate forest, filled with freshwater lakes and a great diversity of plantlife. Conifers, ferns, cycads, horsetails, and early flowering plants filled the environment and indicated a humid, possibly rainforest environment. Periodic wildfires, noxious lake gasses, and volcanic eruptions all lead to regular moments of rapid burial and amazing preservation in this environment - essentially giving us snapshots of how it changed over the course of many millions of years. In the Lujiatun bed specifically, Changmiania was neighbors with Euhelopus, Jeholosaurus, Liaoceratops, Psittacosaurus, Liaoningornis, Daliansaurus, Graciliraptor, Mei, Sinovenator, Sinusonasus, Dilong, Hexing, Incisivosaurus, Shenzhousaurus, and outside of dinosaurs mammals such as Acristatherium, Gobiconodon, Juchilestes, Maotherium, Meemannodon, and Repenomamus (yes, THAT Repenomamus), and the toad Liaobatrachus.

Containment||

| @pacifistghost​ | ➣ Cloud unlatched the huge hook that connected the crate to the helicopter and hopped down from the top of the reinforced crate, dust puffing as he landed. Huffing breaths and soft rumbling growls echoed from the inside of the last of the three crates, making obvious the displeasure of the flight.  Wordlessly, he gave thumbs up to the helicopter above and stepped away, squinting against the sun as the pilot shied off into the sky. He surveyed the area, appreciating the quality of the enclosure. The details and specifications he had -demanded- requested were laid out well. He eyed the containment measures-- they certainly looked the part of being secure, and hoped that they were more than just show for the public. He prayed that they were better than the ones that his charges had outwitted and outgrown.    Strife wasn’t much of a people person, but the animals were a different story.  Understandably, he gave his the respect that a quarter ton killing machine deserved, regardless of his status within the small pride. Still, work came before play and the new handler had some time to kill before they were introduced into their new habitat.    From the corner of his eye, he noticed another person approaching. He sighed, gave a light tap to the largest of the three boxes and tried to put his best face forward, turning to her. The girl was...odd looking, to say the least, but the creature perched upon her thick leather glove drew his attention, and his apprehension dissipated. Beady green eyes shone with intelligence, and a small smile tugged at the corner of his mouth. He rifled through his memory for the right name for the creature. “The base.....Graciliraptor or Gui? Sorry. Cretaceous’s a little rusty. “ He reached a tentative hand towards the spotted reptile, offering the back of his hand for the creature to scent, before looking back up to the girl. “Pleistocene’s my specialty. Cloud Strife. “

Artfight attack #17. The kid belongs to https://artfight.net/~Graciliraptor .

A little context. The character is afraid of fish, and the oc’s owner had a comment mentioning it would be really funny to see him get spooked by something really goofy looking, and this happened.

Are Zhou & Martin’s (1999) “uniquely avian” manual characters known in any other theropods?

Given the focus of Zhou and Martin’s paper, I’ll assume you’re asking about theropods potentially stemward of Archaeopteryx.

A semilunate carpal centered on second metacarpal is also found in Sinornithosaurus, Microraptor, Graciliraptor, and Anchiornis.

A ventrally slanted third metacarpal is also found in Deinonychus (noted in Gishlick’s chapter in New Perspectives on the Origin and Early Evolution of Birds), and it wouldn’t surprise me if it was widespread in tetanurans, given that the third metacarpal overall tends to be positioned ventrally to the second metacarpal within that group.

Four carpals forming a similar arrangement to those of modern birds have also been found in Microraptor and probably Hagryphus.

Simplified articulations between the metacarpals and phalanges are also found in some ornithomimosaurs (e.g., Anserimimus) and scansoriopterygids, and if only the third metacarpal is considered, are common among maniraptoriforms.

The second metacarpal being more robust than the others is also found in some oviraptorosaurs (e.g., caenagnathids), microraptorians, and anchiornithines.

A rounded proximal end of the first metacarpal might actually be limited to avialans, as far as I can tell, but whether it’s really found in Archaeopteryx looks ambiguous to me.

A ridge on the first phalanx of second finger is also found in Sinornithosaurus (noted by Paul in Dinosaurs of the Air) and Deinonychus. I don’t recall any non-avialan theropods in which this has been reported on the second phalanx as well, but it’s far from clear to me that it’s present in Archaeopteryx either.

The distal end of first phalanx of second digit being as wide as or slightly wider than proximal end seems to be pretty common among maniraptoriforms.

You may also be interested in Mickey Mortimer’s critique of Campbell (2008), a paper that built on some of the claims made by Zhou and Martin.
