[dromaeo-sauridae]

tell us more facts about dinosaurs <- has a dinosaur hfx

hm ok heres some random shit

- spinosaurus has gone thru more revisions than almost any other dinosaur

- theres a spinosaurid named irritator because the specimen was so sloppily preserved that barely any details could be made out and it pissed everyone off

- dromaeosaurs were generally small and quick, except for utahraptor (<3) who decided to get 20 feet long because fuck you

- we dont actually know with confidence what dilophosaurus’s crest looked like due to it not being preserved well in any of the specimens (its also MUCH BIGGER than most people realize, and an apex predator of its time)

- ankylosaurs shallow ditches and laid in them, leaving only their bony backs exposed

- carnotaurus’s arms, despite their size, are fully prehensile

- theres an ankylosaur named stegouros that has a sword tail and im not fucking joking

im not sourcing these im on mobile if you want to know more look it up im so tired

Whats your all-time favourite random dinosaur fact?

Hmmmm oh boy--there are, unsurprisingly, a lot of random dinosaur facts I could share... So I think the one I’ll go with is the fact we’ve been able to learn the color of some dinosaurs! In exceptionally well-preserved fossils, scientists have been able to use scanning-electron microscopes to see the cellular structures of things like feathers. By comparing the shapes of these structures to the ones in modern birds, the scientists could figure out the corresponding color in the prehistoric feather and get a general sense of what it looked like in life. The method does have limits, but it’s pretty cool that we have evidence of it at all! ^^

Do you have a favorite dinosaur? :D

More like a favorite family of dinosaurs! I do think pretty much any dinosaur is neat, but my favorite group is the dromaeosaurs--better known by everyone as raptors! My top species out of all of them are probably Microraptor, Velociraptor, Utahraptor, and Deinonychus--which has grown on me a lot because I’m working on making a full, realistic costume/body puppet of it and hope to do educational skits or something with it when it’s done. I’m aiming for it to look like this!

(Yes, that’s generally what raptor dinosaurs should look like and yes it will fit a human person inside it XD)

Anonymous said to undertalethingems: So what do you love most about dinos?

Hmm... i mean, i do think part of the appeal is that they’re cool and impressive like dragons, but they actually existed! but there’s also a huge amount of imagination and puzzle-solving involved in understanding dinosaurs--how did these animals live? what did they look like? how has the earth changed over time? what was it like back then? and all of that is fun for me to think about, research, and imagine what these animals were like. ^^

Well about 3 years ago in 2016 I had bought a sketchbook to make drawings, and for the first time and as a start, I decided to create different sketches of dinosaur head portraits and several other clades related including squamates birds and whatever extinct clade, together forming a parade of diapsids since for that at that moment in time I did not tend to do much paleoart, an attempt to do it by hand without exact references except those that I could remember in my head, a first attempt that wasn't that good, but was something. From there I kept the original page saved while improving with my artistic skills, eventually it had occurred to me to take the page again and rework in the heads, adding and correcting details and also incorporating other species, eventually ending up with something much more varied and complex. At first I was thinking of simply sharing it as a pencil drawing without any other modifications like the previous version, however, I felt it was not really enough to be shared considering that I could do something better or at least decent using digital, so for several weeks I had started painting, changing some misinterpretation of certain animals features and if it was necessary to modify a complete outline if it was not right. And so I ended up creating this new version better prepared, painted and more details, it has also allowed me to practice and experiment with a wider range of textures including scales that I had created for a long time or by hand in drawing, added with photoshop of textures or simply drawn which although it was easy, that not always ended with a good look result, as well as new patterns of colors and mixtures for some dinosaurs. I'm going to leave a list of the species added if people want to known which species is, with a image labeled to locate them. As well some comments on specific species

1) Shoebill (Balaeniceps rex)

2) Diamond firetail (Stagonopleura guttata) I would say I started trying just to draw a random finch due to the conversation on discord with friends but eventually I had to choose a specific species, a good friend suggested me this finch in particular.

3) Kelenken guillermoi Have to say this was the animal that suffered the most transformations since the original drawing as I've changed of sources over time, even though the coloration I nailed the coloration well

4) Deinonychus antirrhopus I tried to experiment with spot patter considering the type of environment that this theropod inhabited, despite the fact that certain colorations of birds of prey fits well for them, thought that different lifestyles would likely make this dromaeosaur coloration not like a bird of prey, so I started to see possible references, feline being the closest and based on certain types of tropical forest/swamp felines.

5) Champsosaurus

6) Tylosaurus pembinensis

7) Tyrannosaurus rex Just to make it clear, it has feathers but they are so thin and small they dont render well

8) Budgerigar (Melopsittacus undulatus): I did this because it is a wonderful bird, some time ago at 10 years old my family had had and even raised some generations of these small birds

9) Yi qi

10) Quetzalcoatlus sp.

11) Broad-billed hummingbird (Cynanthus latirostris)

12) Spinosaurus Before somebody try to start discussing about the lip topic I clarify this is experimental and speculative intent as I've done with another drawing of what it would look like if it had oral tissue around it, pretty much based on the Pike conger eels.

13) Lambeosaurus magnicristatu

14) Dimorphodon

15) Skorpiovenator

16) Deinocheirus

17) Citipati sp. Based from the good unnamed specimen MPC-D 100/42

18) Darwinopterus Originally it was supposed to be a Pterodactylus, however I had mistaken reconstruction of the skull being in fact this sketch based on a Wukongopterid. Coloracion is an "easter egg" of a pal suggestion quite fond of this group of flying animals.

19) Allosaurus fragilis

20) Euoplocephalus

21) Hypsilophodon

22) Tanystropheus

23) Dilophosaurus

24) Tuatara (Sphenodon)

25) Giraffatitan

26) Erythrosuchus

27) Scleromochlus

28) Rutiodon

29) Chasmosaurus kaiseni

30) Green iguana (Iguana iguana) This would be the first animal in the whole parade that I painted scales, after I tried only to use a spray brush that did not work out the way I wanted to, I just made the base picture dark tone and start with a light color to paint the individual scales, I feel good in how this it ended up being.

31) Pelagornis

32) Green Tree Python (Morelia viridis)

33) Pliosaurus kevani

34) Henodus

35) Diplodocus

36) Ophthalmosaurus

37) Pteranodon longiceps

38) Stagonolepis

39) Leopard Gecko (Eublepharis)

40) Anurognathus

41) Mexican mole lizard (Bipes biporus)

42) Silesaurus

43) Petrolacosaurus

44) Shringasaurus

45) Hyperodapedon

46) Teyujagua

47) Plesiosaurus dolichodeirus

Luoyanggia liudianensis

By Scott Reid

Etymology: From Luoyang

First Described By: Lü et al., 2009

Classification: Dinosauromorpha, Dinosauriformes, Dracohors, Dinosauria, Saurischia, Eusaurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Maniraptoromorpha, Maniraptoriformes, Maniraptora, Pennaraptora, Oviraptorosauria, Caenagnathoidea, Oviraptoridae

Status: Extinct

Time and Place: Sometime around 113 million years ago, at the Aptian to Albian boundary in the Early Cretaceous 

Luoyanggia is known from the Haoling Formation of Henan Province, China 

Physical Description: Luoyanggia is an Oviraptor, aka a Chickenparrot - a group of odd birdie dinosaurs with large parrot-esque beaks and squat, chicken-like bodies. Luoyanggia itself is known from only portions of the skeleton, so it’s difficult to say for sure what it would have looked like exactly. However, it resembles Oviraptor in general, one of the more famous Oviraptorids, apart from not having a downturned jaw and having a V-shaped middle of the mouth. This gave it a fairly distinctive looking head. It also had a differently shaped hip from other Oviraptors. In general, it would have resembled other Oviraptors in having a long neck, a fairly large looking head, a squat body, medium-sized wings, a short tail with a tail fan sticking off of it, and average length legs. It was probably around 1.5 meters in length, making it fairly small for a non-avian dinosaur.

As an Oviraptorosaur, Luoyanggia would have been covered in feathers, including advanced (but not quite bird-like) wings, and a tail fan connected to a pygostyle. Pygostyles are fused, shortened tail bones seen in modern birds and Oviraptorosaurs. This structure evolved independently in both groups and is used to move the tail in more complicated ways, such as in sexual displays and in flight. It is possible that Luoyanggia also had some sort of crest on its head, though none has been preserved.

Diet: Luoyanggia would have been omnivorous, eating a wide variety of food material, though primarily feeding on plants rather than meat.  

By Ripley Cook

Behavior: Though Luoyanggia is not well known, we can glean some of its behavior based on its close relatives. Oviraptorosaurs such as Luoyanggia are known to have taken care of their young extensively, creating large nests with eggs laid around the edge, from a single oviduct. Luoyanggia would then have sat in the center of the nest, and used its wings to keep the eggs warm. This brooding method is very similar to those employed by modern birds. The eggs of Luoyanggia would have been elongated and ovular, rather than small and round. It is also possible that the eggs may have been colored as well, potentially a deep blueish green.

As a feathered, warm-blooded animal, Luoyanggia would have been fairly active in its environment, and probably would have used its feathers not just to cover eggs, but also to display to other members of the species - both by using the tail fan in sexual display, as well as the wings. The wings were not large enough or complex enough, however, to be used on behaviors as seen in Dromaeosaurs and even more birdie dinosaurs.  

As an omnivore, Luoyanggia would have been partially opportunistic, looking in its environment for any possible source of food.

Ecosystem: Luoyanggia lived in a fairly muddy environment, and was probably the site of some sort of freshwater ecosystem, though what specifically is not entirely clear. A swamp or lake seems fairly likely. Other dinosaurs are known from the formation such as the titanosaur Xianshanosaurus, the almost-titanosaurs Yunmenglong, Huanghetitan, and Ruyangosaurus, the ankylosaur Zhongyuansaurus, and a potential large theropod that would have been the main predator of Luoyanggia.

Other: Luoyanggia has never been properly analyzed in a phylogenetic study, so its position as an Oviraptorid is somewhat suspect.
