#ophiacodon

[slogokonnor99]

Time for the monthly drawing recap!

In this month:

- the bellkeeper and Hilda locate a lost herd of Centrosaurus just as the weather begins to worsen

- out of its territory, the spider frog must now fight for its life as a Giganotosaurus emerges from the forest. It's better for Johanna, Hilda, and Twig to get out of the way

- Hilda and Twig watch from the safety of a tree as a male Yutyrannus tries to court a female

- just before this Ophiacodon could strike, Frida grabs its tail to distract it, allowing David, who's been turned into a frog, to leap for safety

- Hilda and David watch as Frida tries to use the mind connection spell on a tame Liopleurodon, the latter cheering her on

I got a new sketchbook and pencil!!! So I made lots of happy doodles! :3

The ophiacodon and dicynodont were from memory, with the latter being particularly innacurate… and the last one was a doodle of a cockatoo squid, cause I just learned about them and how fucking big they get on Twitter. 4 meters long!!! Got damn silly giant

Retro vs Modern #15: Dimetrodon limbatus

With its prominent sailback Dimetrodon is one of the most iconic prehistoric animals – and one that still frequently gets mistaken for a dinosaur, despite being closer related to modern mammals.

1870s-1980s

The first known Dimetrodon fossil was an upper jaw fragment found in Canada in the 1840s, but at the time this specimen was thought to represent a dinosaur. It wasn't until the late 1870s that species like Dimetrodon limbatus (initially called Clepsydrops limbatus) from the Midwestern and Southern United States were recognized as belonging to a much older and different group of animals given the name "pelycosaurs".

While some paleontologists did propose pelycosaurs as being ancestral to mammals quite early on, for several decades the prevailing view was actually that they were an ancient branch of rhynchocephalian reptiles closer related to modern tuataras. From the 1910s onwards pelycosaurs were finally linked back to mammals, with their similarities to the therapsids placing them as early members of the synapsid lineage – although all these early mammal-relatives were still considered to be derived from reptiles, and "mammal-like reptile" became a commonly-used term for them. 

As a result reconstructions of Dimetrodon during this time period usually depicted a highly reptilian and heavily scaled lizard-like animal, with a sprawling belly-dragging pose, protruding crocodilian-like teeth, and a highly shrink-wrapped sail on its back modeled on those of some modern lizards. Some earlier images also showed a short stumpy tail, since Dimetrodon's longer tail proportions weren't confirmed until the 1920s.

2020s

During the late 20th century new classification techniques led to the messy concept of "reptiles" being properly redefined as sauropsids, and synapsids being recognized as an entirely separate non-reptilian lineage of amniotes. Along with new studies and discoveries this has resulted in our understanding of Dimetrodon changing a lot in the last few decades, moving away from a heavily reptilian interpretation and instead letting it be its own weird "protomammal" thing. 

We now know there were at least a dozen different species of Dimetrodon living during the early-to-mid Permian, about 295-272 million years ago. Most of them are known from North America, but an additional species discovered in Germany suggests this genus ranged further across Pangaea than previously thought.

Dimetrodon limbatus was one of the larger species, about 3m long (10'), and like other members of the genus it had a tall narrow skull with high-set eyes and two distinct types of teeth in its jaws. The structure of its nasal cavities suggest it had a good sense of smell, and like the related synapsid Ophiacodon it may have had a closer to "warm-blooded" metabolism than previously thought.

It would have had a very poor sense of hearing, however, and probably didn't even have any visible ears on its head. It may have been functionally deaf to air-borne sounds entirely, only able to detect vibrations by pressing its lower jaw to the ground.

No skin impressions are known for Dimetrodon. Scaly reptile-like skin has been found on varanopids, a group traditionally classified as very early synapsids – but some recent studies have suggested they were actually part of the true reptile lineage, so their extensive scaliness probably doesn't apply to synapsids like Dimetrodon after all. There is some possible evidence of rows of square or rectangular scale-like scutes on the underside of the belly and tail in pelycosaur-grade synapsids, but otherwise the next-closest known synapsid skin comes from the distantly-related therapsid Estemmenosuchus, which seems to have had smooth glandular skin similar to a hairless mammal.

The characteristic back sail, formed by highly elongated neural spines on the vertebrae, is now thought to have been covered in a different pattern of soft tissue than older reconstructions depicted. The texture of the bone along the spines' length shows that at the base they were deeply embedded in the back musculature, then further up they were covered by skin webbing, but then at the tips they may actually have been unwebbed and free-standing, giving a much spinier profile.

While the sail was traditionally assumed to be used for temperature regulation, more recently this has started to seem less likely. The sail doesn't seem to have been quite as well-supplied with blood vessels as previously thought, and there's a lack of direct correlation between sail size and body size in different Dimetrodon species and age classes. Instead this structure may actually have been used for visual communication and display, and could therefore have been quite flashy and brightly-colored.

Fossilized trackways also suggest that Dimetrodon didn't move with a low lizard-like sprawling gait but instead with something more like a crocodilian "high walk", with its limbs much closer to upright. It was probably a fairly active terrestrial predator and would have eaten a wide variety of other smaller Permian animals, with its teeth having been found in association with the remains of the amphibians Eryops and Diplocaulus and the freshwater shark Xenacanthus.

Brickosaurs Evolution - Ophiacodon

Another of the smaller end models, this is Opal the Ophiacodon!

These sizes are always the most challenging to make interesting; too big for really intricate details but too small for elaborate color schemes. But I’m really pleased with how she came out! She seems happy about it too. :D

i have been drawing some of my favourite biologically inexcusable hybrid animals from jurassic world alive, which is a game i have been playing on my phone lately. this is ‘ankylocodon’, a fairly straightforward “we just put some armour plates on a synapsid” combination of ankylosaurus and ophiacodon, and the incomprehensible ‘diplotator’, which is supposedly the result of combining diplocaulus and irritator. i dont know why they decided to give it massive spikes, or a dorsal fin, or an enormous overbite, or iridescent rainbow stripes, or a head the size of its entire body, but i am really, really glad they did, and i think whoever designed it deserves a raise

[zin0dious]

Some other aminals I recommend that aren't dinosaurs are Rhamphorincus, Nundasuchus, Sarcosuchus, Kaprosuchus, Postosuchus, Tricondonta, Ophiacodon, Entolodon, and there's probably more I'm missing. One thing Jurassic Park is good for in terms of their animals is they have a HUGE diversity with their pics. They literally take anything from the past and make it one of their animals. Why not take a few names from them?

Rhamphorhynchus is one of my favorite prehistoric animals, and probably my favorite pterosaur. They’ve got some real funky teeth that I love.Postosuchus is bizarrely adorable?? i love it a lot. Weird lil potato crocodile thing.Triconodonta is also fantastic, wasn’t that the little thing that the Dinaurians turned people into in the first game w/ the regression ray or w/e? Rosie got turned into it once, right?Entelodont is also fantastic. a good crazy-lookin wild boar dude.

those are all really cool and I like em a lot :O they’d definitely be interesting to try out after i finish the current batch of synapsids.

10 things I’m Excited for in the new National Fossil Hall (Part 3)

Part 1

Part 2

The Smithsonian National Museum of Natural History’s new paleontology exhibit opens in a little over a year. Here are some things to look forward to:

8.       So many new specimens

The National Fossil Hall will feature hundreds of fossil specimens, and a plurality of them have never been exhibited before. Most are real specimens straight out of the museum’s collections: examples include the horse Equus occidentalis, the skull of Odobenocetops, a drawer full of cave-dried ground sloth dung, and a near-perfect Ophiacodon (pictured). Other newcomers are casts made from specimens at other museums: Euoplocephalus, Eoraptor, and the four-legged proto-manatee Pezosiren are among them.

9.       A recreation of Pocahontas Mine

The Carboniferous section of the exhibit will be centered on a recreation of the Pocahontas coal mine in south-central Virginia. Last fall, a Smithsonian crew took casts of the mine’s walls, which are covered in impressions of ancient spore plants.

10.       The other side of the roadkill Stegosaurus

Last but not least, we will finally be able to see the other side of the Stegosaurus stenops holotype. Lovingly called the “roadkill Stegosaurus,” this skeleton was recovered in Colorado in 1887, and is significant because it was the first Stegosaurus found with its plates in their life positions. Unfortunately, the skeleton has been displayed on the floor since 1917, making the left side inaccessible to researchers for a century. Plans for the new exhibit place the roadkill Stegosaurus  in a vertical case, allowing both sides to be inspected.

As promised, here are my dinos. The top 8 are my ‘team’, but that’s about as much choosing as I do; when you enter a battle it picks four from that pool and you have to work with what you get. I actually kind of like it.

Details below cut.

So from left to right, top to bottom:

Stegosaurus, velociraptor, allosaurus, einiosaurus, nundasuchus, ophiacodon, ankylosaurus gen 2*, sarcosuchus

Euoplocephalus, diplocaulus, tarbosaurus, majungasaurus, suchomimus, lythronax, tanycolagreus

Erin has more, including some rares (all of mine are common).

For anyone wondering why I have a level 1 ophiacodon instead of that level 7 euoplocephalus...well, the latter is really not that great in battle. And when you only have two moves, neither of which do anything special, it’s not a great choice. Ophiacodon (and it’s rare counterpart, dimetrodon) has a passive ability called ‘Immunity’, which prevents it from dealing with special effects, like being slowed down (which can be the death of you), bleed damage, vulnerability (defense drops), or stun (flinch). I think it prevents stun. Don’t quote me.

But basically for me if my four for battle include velociraptor (fastest dino in the game which is also OP but can’t handle two hits) and stegosaurus (bulky but relatively fast, and has an attack that slows your opponent down, possibly changing the game) I feel pretty confident. Allosaurus is also pretty great (bypasses armor, which is additional defense on some dinos).

*Gen 2 dinos have alternate coloring (gen 2 diplocaulus is red, but rare), are often a different rarity, and can’t be used to make hybrids.

Those timers are the two incubators I have going. One just exists, the other is won in battle. You can only activate one battle one at a time, and you can only hold four.
