To the delight of many, Prehistoric Planet came back this year for a second season, bringing with it a whole cast of new and returning maniraptoran dinosaurs. How do these depictions line up with the latest science? I discuss this in my review.

[slogokonnor99]

Time for the monthly drawing recap!

In this month:

- now that Phinium is back on the human world, he must learn new basic rules, like not to steal food in front of a territorial mother Gastonia

- a pair of Imperobator face a critical decision: do they fall for David's bait and chase him, or do they wait for Frida to lose her grip?

- a Corythoraptor ruins Woodman's lazy day by blocking the view

- this Kaprosuchus basks between David and the ball he accidentally kicked into the creek. Getting it back will be much trickier

- Astrid and the pooka have a morning problem, as a Nasutoceratops has fallen asleep on the former's front door

Known for its tall, recognizable, cassowary-like crest, Corythoraptor jacobsi was a large oviraptorosaur also from the Nanxiong Formation of Late Cretaceous China. Corythoraptor’s crest was heavily pneumatized (full of air pockets), even more so than the modern day cassowary’s crest. This likely made the crest very light and fragile, even when covered by a keratinous sheath. It probably served a purpose similar to a cassowary’s crest: for display, to dissipate heat, and to detect low-frequency sounds.

The first, and only, known specimen was found to be at least 6 or 7 years old, having gone through seasonal growth spurts. This indicates that it lived in an environment that experienced fluctuating rainy and arid seasons. Corythoraptor likely used its toothless beak for eating plants, nuts, and seeds. However, since the Nanxiong Formation was home to many different species of oviraptorosaurs, it’s possible each one specialized in different types of food to avoid competition.

Corythoraptor had its first big spotlight in the documentary Prehistoric Planet, where it was seen eating Ginkgo seeds and being hunted by the long-snouted tyrannosaurid Qianzhousaurus, the apex predator of the Nanxiong Formation. It was also seen in the second season having its eggs stolen by the dromaeosaur Kuru kulla. While a welcome reversal of the common trope of always depicting oviraptorosaurs as egg thieves, Kuru did not live in the Nanxiong Formation, and was instead native to the slightly older Barun Goyot Formation of Mongolia. Corythoraptor would have instead shared the Nanxiong with other oviraptorosaurs like Tongtianlong, Ganzhousaurus, Huanansaurus, Jiangxisaurus, Shixinggia, Nankangia, and Banji, as well as therizinosaurids like Nanshiungosaurus, macronarian sauropods like Jiangxititan, indeterminate hadrosaurs, turtles, lizards, and the crocodilian Jiangxisuchus.

Something that has both fascinated me and frustrated me to no end as of late are the lacrimal crests of allosauroids and other such theropods. No living theropods, to my knowledge, possess such structures. The closest analog I could find were Geese. I'm being driven up a wall trying to figure out what they would have been covered with in life. How would they have been incorporated into the face of the theropod? What display structures could they support? Air sacs, keratin, or caruncles? How pneumatized were they? Were they even for display? Most paleoartists just reconstruct them as odd stones sitting on top of the animals head, or say they were just for shading the eyes, but that can't be it, right? It feels like something is missing.

As a Paleoartist, is there anything you can say on this? Because I don't know nearly enough.

Oh boi, this is a tricky one.

Cranial ornaments come in all kinds of shapes, sizes and surface textures. For Allosaurus it seems likely that they simply had keratin sheets on top of the lacrinal crests, at least that's what the rough surface and striations suggest. However it also seems like air sacs were reaching up from the antorbital fenestra

This is how I would reconstruct that part of Allosaurus in the moment.

There could have been more though, you can see in this photo of the skull of Big Al II that this animal had large opening behind the lacrinal crests, so there could have been other structures involved.

Maybe even better to look at is this 3d scan of Arkhane, from Brussels.

This could have been related to theroregulation, more display structures or simply further weight reduction.

There is quite a bit of wiggle room when it comes to the interpretation of dinosaur facial features and there is way too much already published and at the same time too little to put it all into a single blog post.

Also not all dinosaurus follow this patters, the cranial crests of oviraptorosaurs show no good indication for keratin crests for example. So it's better to say good bye to cassowary interpretations of these animals and instead cover them in skin and/or inflatable sacs, because these hollow chambers appear to be extensions of the sinuses. (my version of Corythoraptor on the right, Citipati from Wikipedia on the left.)

And then again in other theropods like Abelisaurs we see very rugose skull tops but without the striations you see on the lacrinals of Allosaurus, potentially indicating large scales. Here my, slightly over the top, interpretation of Skorpiovenator. And even then: within abelisaurus you have stuff like Carnotaurus which shows clear signs of keratin sheets on its horns.

This all has been complicated in recent years with new methods in bone histology, because as it turns out the internal structure of a bone can tell us stuff about it's outside, that's how we for example found out that Amargosaurus neck spines were no horns and probably conected with soft tissue, or that the osteoderms of notosuchians were covered by skin like in leatherback turtles.

Going back to Allosaurus and other allosauroids. Keratin sheets, scales, air sacs, all these were probably present in these animals, but their exact distribution is still a question of debate.

Here a paper from a few years back that maps para-nasal sinuses in extent and extinct archosaurus which gives you a little idea how complex their internal anatomy could get

I'm currently working on something quite detailed so in the meantime here is the first digital artwork I made. Corythoraptor from prehistoric planet.

I love prehistoric planet so so dearly but i do wish that they made the animals a little less gray.

Especially in cases of animals that are theorized to have sexual display traits like frills or crests?? They put some color on them but compared to real life animals (especially reptiles & birds!) they are just sooo dull.

Nanuqsaurus was especially disappointing for me. Maybe it's just because it's normally depicted as some kind of white color, but i feel having the opportunity for such a unique color on this dinosaur and making it mostly the same grayish brown as so many other dinosaurs in the show was a missed opportunity.

Part of this is definitely the filter and lighting they put over certain scenes to make them look more 'natural' i suppose. I think the male hatzegopteryx's crest is actually very beautiful, but unfortunately due to the lighting of the show it often appears so much more drab and dull than it should be, even in broad daylight .

(color in show vs art by ttorroo on instagram)

This is a major reason the corythoraptor design stood out to me, because they were just so bright and beautiful in comparison to everything else in the show! Every time they were on screen i thought it was amazing to get to see these dinosaurs in such vibrant color! This shows that they /can/ depict dinosaurs in this way at least.

And i feel as though the only reason they /were/ blue is because they were based off of the modern cassowaries (one of which i got to see in person recently, they are a GORGEOUS blue. So much brighter than you would expect, heres a picture)

I just feel like, even though i love prehistoric planet, its quest to be overly 'realistic' holds it back in this area at least. The only animals they were willing to make super vibrant were the ones they based on a living similar bird, instead of considering that if the bright colors of a cassowary are possible, there's nothing that says that other bright colors could be possible on other types of dinosaurs.

Especially considering the colors of other birds! If they wanted to base the dino coloring on real life animals, they could have been inspired by other kinds of birds. Just because cassowaries are more 'dinosaur-like' doesnt discount the fact that birds are an incredibly diversely colored and patterned group of animals. There is plenty of potential for other colors in dinosaurs when looking at modern ones.

In fact, i would argue that the fossil evidence we have shows that dinosaurs could have been more brightly colored and distinctly patterned than the ones in the show, at least. While there haven't been bright yellow or blue dinos found, there has been evidence of brighter reds and browns, some greens and purples, iridescent like feathers, and more distinct patterns like stripes on several dinos.

It kind of baffles me how they were able to make leaps like the dreadnoughtus air sacs, but they weren't willing to make the dinosaurs a little brighter? I mean, so much paleo art nowadays depicts dinos in vibrant colors, i dont think it would be too much of a stretch.

Tldr, i love prehistoric planet and i think it has done a lot for the perception and depiction of dinosaurs as real life animals, i just wish that it didnt associate looking 'realistic' with 'looking gray' as much as it does, especially considering the amount of potential traits for sexual display dinosaurs had, and the colors of living birds and fossil evidence of dinosaur colors.

I was interested in “Badlands” which I had learned recently that it’s not just a national park in the southern U.S., but rather an area of eroded land where resources are rare or none and are found in many places around the world, but you’d be surprised what could survive in those conditions.

We start with a bang as a herd of female titanosaur sauropods called Isisaurus trek through a volcanic hotspot in India to lay their eggs in some epic imagery, reminding me of the Dreadnoughtus from last season. And I loved learning about why they go there as well because there are no predators around, the soil is perfect for thermal regulation and their necks will hover over the poisonous gases coming out of the vents.

We return to Mongolia to see a family of Velociraptors find food for their recent brood and some Tarbosaurus creating chaos at a traveling herd of Nemegtosaurus while moving through a canyon. The raptors take advantage of it and hunt a group of Prenocephale who were with the herd. The babies were cute though.

Then we focus on a group of male Corythoraptor who take their position in protecting the eggs that the females laid over the extreme heat during the day. While they rejoice in the cooler nights and some look for food, we’re introduced to a new dinosaur called Kuru kulla, a raptor relative who waits for the right moment to snatch a few eggs thanks to its keen eyesight. She also grabs one for her young and we watch them figure out how to open it with charming results.

In another spot in Asia, we learn of the lives of the nomadic Tarchia, ankylosaurs who can go without food or water for days and must hurry when they get low. A sibling duo deal with Prenocephale and an older, larger individual for their share of an oasis.

Surprisingly, we go back to watch the baby Isisaurus crawl out of the volcanic soil that kept them warm after their mothers left the nesting grounds, months ago. It was rather gross learning that their first source of food was the droppings left by the females which had plant material in them, and that the seeds they dispersed grew into flowers further ahead, but at least the females were thinking about their children, kind of. I was reminded of the baby sauropods from “Walking with Dinosaurs” and “Dinosaur Planet” in terms of the drama the babies went through in traveling to better conditions and face many dangers including hot springs and hungry Rajasaurus. Plus, the squeaks the babies made were harmonious and tragic at the same time, as if foreshadowing what’s to come.

Despite some good moments and direction, it begins the issues that I mentioned earlier which kind of downgrade the expectations of more epic moments. I guess it’s the nostalgia from the awesome “Deserts” from last season. And perhaps I wish we saw more areas with badland regions besides Asia.

3/4 stars.

Let's hope that 64 millions of years later nobody mistakes this kind act of parenting for simple burglary.
