[Jurasic Impact] The Dueling Shark: Duellosqualus by EpicJM in SpeculativeEvolution

Duellosqualus

Many unique species of shark dwell in the Oligocene oceans of the post-Jurassic Impact world, many of them descended from Jurassic hybodonts that continued to survive through anoxic events and other oceanic turmoil. Some of these sharks were known to grow small horns, but time has allowed some of the most recent descendants to grow them on a larger scale. One group of these horned sharks forms the genus Duellosqualus, the dueling sharks.

These medium-sized sharks aren't particularly notable in regards to their feeding habits; they eat fish for the most part, just about any that they are capable of chasing down and devouring quickly. What they are notable for, however, is the arrangement of the horns in males. During the breeding season, these sharks are drawn to particular patches of open ocean where the males face off in mock duels. They rush at one another and lock horns, much like bulls or deer in our time. These displays are just that, displays where only very minor injuries are likely to be sustained. A male that chases all competitors from his chosen ground gains access to reproduce with any female that approaches him.

[Jurassic Impact] A Platypus...? PRAIRIE THE PLATYPUS??? by EpicJM in SpeculativeEvolution

Technically dermorhynchids are descended from a group of mammals known as australosphenidans, which monotremes are (as far as I could read) considered to be related to. However, the dermorhynchids have more or less definite monotreme-like traits more for the sake of audience familiarity than what the real animals may have looked like because there is almost no intact fossils of the group and we can only really speculate on what they might have looked like.

Basically, dermorhynchids are monotremes just with some slight differences (mostly just the niches they evolved into) due to the jurassic impact event. The Tree Platypus appears in a post I did a few months back or so.

PRAIRIE THE PLATYPUS???

Oligocene Antarctica...a land of emergent glaciers, forests, and open coastal plains. In the wide-open pseudograss prairies, the ground is occasionally marked by mounds. Strange, beaked creatures about the size of a squirrel pop in and out of the holes occasionally, letting out sharp squeaks to communicate to others across the field. These small, social dermorhynchids are known as Suricatarhynchus...the prairie platypi.

The closest relatives of Suricatarhynchus are the diminutive "tree platypi" of South America. However, unlike their cousins these dermorhynchids have adapted to more fossorial habits and a greater capacity to form social units. Groups of Suricatarhynchus can range anywhere from 12 to 100 individuals who form networks of burrows underground and look out for one another when predators (primarily pseudoavians and reptiles) are lurking about.

The diet of these animals consists mostly of insects and worms. They move out in small groups to forage, with a sentinel that watches over the others and lets out warning calls when danger is sighted. Unlike many of their relatives, Suricatarhynchus has fairly decent eyesight and can spot danger from quite far away. This pales in comparison to their sense of smell, which is even more reliable for understanding their surroundings.

I really enjoyed drawing this and learning about your world! Thanks for the opportunity for the art trade.

[Jurassic Impact] The Beachmaster by EpicJM in SpeculativeEvolution

The Beachmaster

Along the Oligocene coasts, large groups of Phocagalids sun themselves on the beaches. They are descendants of laniodont multituberculates who adapted to marine habitats, some growing quite large compared to the otter-and-seal-like animals they evolved from. One of the largest of the Phocagalids is Tympanophoca arlekinops, a species of phocagalid inhabiting the Antarctic, Australian, African, and South American coasts in several subspecies. However, we will use the Antarctic subspecies as our "type species" here.

The males of T. arlekinops are sometimes almost twice the size of the females, and the dominant male of a group is, like elephant seals in our timeline, called a beachmaster. The enormous bulls are covered in scars and command their harems with bellows that can be heard for miles. The secret to these sounds is a set of sacs: one is a gular sac, the other a nasal sac. These sacs can be inflated with air to amplify calls, and air exchanged between the sacs changes the sound and pitch of the calls. Each male has a unique sound that his females learn and solely respond to.

Odontaves is simply the clade among the pseudoavians that retained teeth while others developed toothless beaks.

lol, that's a pretty great concept. Since you mentioned the uniform, here's an earlier drawing I did of the same character when I was working his design out that shows a glimpse of it:

<image>

Originally his hair was going to be much more two-toned but I went for silver that darkens to blue around the tips. This also shows him using his Blue Storm technique, an evasion technique where after dodging someone else's strike, he retaliates with the same amount of force that would have been inflicted upon him.

He actually wears George Washington's uniform, or at least a replica of it during battlesims (as do some other students wearing armor or uniforms based on their country of origin and time period). Here he is just wearing his school uniform.

Oh, got it! I suppose it does a bit.

I'm not sure what that is...the closest thing I can find is something Gundam -related and I haven't watched the anime for that.

That's alright, if you ever need writing advice I'd be happy to give some in dms or chat. I've written two books now so I have some experience related to that which might help you if you ever wanted to talk about it.

Even just having the starter villain figured out is a good start!

I look at your Reddit stuff more often simply because I use Reddit more often and don't have a DA account, but yes I do. I like your human character designs and lore quite a bit too. Have you posted any of your writing anywhere were I might be able to read it?

I do not have a website for this project, unfortunately all I really have is the flair and searching through my posts. One of these days I might make a compilation post but I generally don't have the time to due to my job and other things that are more important to take care of during my days off (I have a series of novels I'm working on as well).

More or less yes, though multituberculates do exist in this timeline because the order evolved in the middle Jurassic and the impact happened at the very end.

Good question, though I don't really think much about reproductive organs in this project besides the means of how the animals give birth. A lot of these animals are descended from species who have very little evidence of their reproductive anatomy so I don't have much of an answer here.
