#ceolophysis

[datgreenmonstah]

This is my rough idea for the reference designs so far. Going off the book as close as i can to where it makes sense, using a mixture of reptile/bird/amphibian for markings/colors to fit the descriptions better, like ceolophysis with a basilisk lizard since its mistaken for one with how the biologist mistakes it for one until he see’s the girls drawing.

Will be doing other colors like for the velociraptors.

This comic will have an alternative more scientifically accurate version after the book accurate is finished so the designs fit more of the modern day understanding of the animals. Why dakota raptor is chosen since it fits size and description and location on where its being dug up and looks like an oversized velociraptor.

Will eventually get to the characters and the buildings/vehicles

Also including previous sketches/ie size chart and other rough ideas

Im still working to do this, it’s just getting juggled around with other projects as well as while I’m dealing with health stuff and family, so sorry if this is taking awhile.

Sorry Friends!

I know this unannounced hiatus has lasted a few months now, and it will be a few more.

My current living situation is... Unfortunate. At the moment. In the meantime Big Red and Co. have been tucked into a box in my storage unit for their safety.

It took me longer than I'd like to have made this post to explain my absence, but that's just how it goes with mental health sometimes. Im doing better now, and focusing on the projects I can manage!

I did collect some new friends on my recent trip to boulder to see a show (planned and budgeted for before I started this blog), you can have this preview for now until it's time for Big Red to return!

This member is a ceolophysis, and they don't have a name yet! Maybe you all have some suggestions? :)

A Hundred Some New ATOM Kaiju Pt. 1

So, for about five years or so now I've had, oh, a hundred or so ATOM kaiju sketches that have just been sitting waiting for me to ink and color them. But I've come to accept that I just cannot produce art as quickly as I did in my twenties, and the prospect of me actually finding time/energy/a lack of throbbing pain in my hands to do so is, uh... slim. And I think that's kind of sad, because these guys deserve to have some time to shine.

So, over the next couple days (because I'm pretty sure Tumblr's image posting limit won't let me do it all at once) I'm going to share them with you, for my own enjoyment. And we'll start, as is proper, with some retrosaurs.

First, some from the tiny tyrant clade. We've got a Jurassic Park dilophosaur homage and one inspired by Saltopusuchus (my dad's favorite dinosaur from his childhood dinosaur book, purely because he pronounced its name "SaltopoSUCKus" - unfortunately for my dad, saltoposuchus is actually a crocodylomorph, though there is a dinosaur named Saltopus. Maybe his childhood book was confused?). There's a trio of ceolophysis-inspired ones who I envisioned as a sort of kaiju Team Rocket - they're got arm membranes to show that they're sort of a missing link between Tiny Tyrants and Flying Tyrants, and because it makes them look like they've got little dramatic villain capes. And a more 80's style dromaeosaur-inspired retrosaur than Colossaraptor, who obviously takes more from 90's retrosaur dromaeosaurs/JP raptors.

Next, a pair of Flying Tyrants. The first was a result of me looking at a Quetzalcoatlus skeleton and thinking just how fucking weird their proportions were, and the later is inspired by rhamphorhynchus, perhaps one of the most fucked up little guys in the fossil record.

The final four of this section: a primitive carnivorous retrosaur inspired by the Crystal Palace Megalosaurus statue, a Bronton-sized True Tyrant inspired by the exaggerated depictions of Giganotosaurus in pop culture, a shark-like true tyrant inspired by Carcharadontosaurus, and finally... Tirontus. Tirontus is specifically inspired by the the 1960 film adaptation of The Lost World:

Which uses perhaps the most reprehensible of all atom age special effects, slurpasaurs. And I feel like even in its time no one bought this shit - any child would take the scene where Claude Rains says, "Look, a tyrannosaurus rex!" at what is clearly an iguana with rubber horns glued to its head and say, "That's not at all what a T.rex looks like. I've read books, dude." It's ridiculous.

And wouldn't it be funny if there was an ATOM story where some scientist finds a retrosaur kaiju that looks like, well, just a big lizard, and tries to pass it off as another Tyrantis? "No, no, this isn't just a big iguana, it's a tyrannosaurus rex!" So that's Tirontus, the false Tyrantis.

Hi Dinosauraday, as a biologist (in training, finishing up my bachelor's degrees (plural) atm) I love you and your work here to spread the good word of dinosaurs including the extant ones!

I wanted to ask, have you heard of/watched/do you have an opinion on PBS Eons on YouTube?

Also just because it's fun to say, my favourite kind of Dinosaurs are Ceolophysis! Keep up the good work!

Thank you! Good luck on finishing your degree!

I really enjoy Eons. They sometimes don't communicate something the way I would, but they make great content and really bring a good understanding of prehistoric life to a lot of people

Here's the google Docs, but I'm gonna upload it tumblr as it's own video and link it back here.

i’m watching the behind the scenes feature on the walking with monsters dvd and there’s just a random clip of a coelophysis doing a kickflip

Dinocember day 15: Coelophysis

Sighting by two terrified campers cabin-goers

[thecoffeeisblack]

Tattoo concept variations. I'm leaning for just solid black, but I'm playing for it moving into fall leave colors, but I think with my skin it's probably going to work best as a black and white.

Much of my journey for this trip has been following collections and ancient trackways, and looking at the scaled down modern dinosaurs we are living with now. So I sampled some 3 toed Jurassic footprints, with Allosaurus being the largest, Eubrontes gigantes (possibly Dilophosaurus or a close cousin), Ceolophysis, and the last 2 are little ones are modern Corvids, a Crow (Corvus brachyrhynchos), and a Bluejay (Cyanocitta cristata).

I know it's not as chronologically accurate as I would like, but the visual sizing works, and the time period kind of does for the types of rocks around the Connecticut River Valley and Western, Massachusetts, plus I get to use the Eubrontes which is a specific example from that area.

Anyway, I'm thinking of getting it done tomorrow at the smaller scale in the 4th image.

I finally revamped and finished an old pic I did for Halloween a few years back, and I’m glad to call it done! Ceolophysis, a small carnivorous dinosaur from the Late Triassic, known from dozens of fossils from Ghost Ranch, New Mexico--seen here revisiting its old haunts...

Daemonosaurus chauliodus

By José Carlos Cortés

Etymology: Demon Reptile

First Described By: Sues et al., 2011

Classification: Dinosauromorpha, Dinosauriformes, Dracohors, Dinosauria, Saurischia, Eusaurischia, Theropoda

Status: Extinct

Time and Place: Between 205 and 202 million years ago, in the Rhaetian of the Late Triassic 

Daemonosaurus is known from the Siltstone Member of the Chinle Formation in New Mexico 

Physical Description: Daemonosaurus is an interestingly little dinosaur, and an enigmatic one, with its placement within the dinosaur family tree holding significant importance for how dinosaurs organize themselves in their initial diversification. This was a small, bipedal dinosaur, only about 1.5 meters long and weighing no more than 22 kilograms. While its body was relatively normal of a dinosaur at that time - longer legs than arms, arms built for grasping, long tail and stout torso - its head was downright bizarre. The skull was very short and box-like, rather than long and narrow or long and rectangular like other predatory dinosaurs of the time. Daemonosaurus also featured very long and large teeth in the upper jaw, and teeth that projected forward out of the mouth from both jaws - in short, it looked fairly buck-toothed. It also had a slight notch in its jaws, which could have been used to grab hold of struggling food and trap it there. It also might be an example of paedomorphy - while the head seems fairly juvenile (including rather big eyes), the rest of the body has the fused bones of an adult. As a small dinosaur, Daemonosaurus would have been covered in fluffy protofeathers for thermoregulation.

Diet: Daemonosaurus would have primarily eaten small animals like early mammals and smaller reptiles, though baby dinosaurs from other species wouldn��t have been off the menu. 

By Michael B. H., CC BY-SA 3.0

Behavior: Daemonosaurus, being a smaller theropod, wouldn’t have been a very bold predator. Instead, it probably waited in the shadows and undergrowth a lot, looking for a moment to strike at its prey. Hiding in the bushes, it was able to stay safe from larger predators, which frequented the environment. It probably would use its hands and mouth to grab struggling prey, and also defend itself from danger. With its very large eyes, it’s even possible it was somewhat nocturnal, and did most of its hunting in the safety of night. It probably took care of its young, though of course without fossil evidence of such it is hard to tell; and it would have been a fairly active, intelligent animal in its habitat.

Ecosystem: Daemonosaurus lived in the Siltstone Environment of the Chinle Formation, a famous ecosystem showcasing the rise of dinosaurs within North America at the end of the Triassic Period. Daemonosaurus is known from one of the later ecosystems of that formation, which makes its position as a fairly basal theropod somewhat surprising. This was a seasonally arid floodplain, with trivers that would occasionally flood and alternate between that and drying up completely. As such, the plantlife around the floodplain was mostly hardy ferns, ginkgoes, horsetails, and cycads - as well as a fairly dense forest of pine and other coniferous trees. Here Daemonosaurus shared its environment with many other Triassic weirdos, such as the Drepanosaur (lizard-monkey thing) Avicranium, ray-finned fish such as Hemicalypterus and Lophionotus, the phytosaur Redondasaurus, the small Aetosaur Stenomyti; and other Dinosauromorphs. There was the Silesaurid Eucoelophysis, the Lagerpetid Dromomeron, and another theropod dinosaur, Ceolophysis. 

By Scott Reid

Other: Is Daemonosaurus a theropod? Probably. But its head is so weird - and its whole body, too - that the position of Daemonosaurus is a question within the early diversification of dinosaur group. Indeed, Daemonosaurus often changes how a phylogenetic tree turns out. This weirdness is something to keep an eye on for now, because the jury is still out - though basal theropod seems likely. And what a weird theropod lineage it represents!
