FC Deltatheridium by Midiaou FC Deltatheridium by Midiaou
    Deltatheridium is a small, approximately 6 inch long Basal Metatherian. Despite its tiny size, it surely wasn't an animal a small dinosaur would want to come across. Its teeth were gnarly and make modern opossum teeth look cute. And it surely left its mark in the fossil record in the form of trace fossils. Precisely, the mangled skull of Archaeornithoides. The holotype, which mostly consists of maxillary bone and dentary shows that the animal did not have a pleasing end. A puncture wound in the maxilla matched the teeth of a weasel sized Deltatheridiid. And what Deltatheridiid happened to be a contemporary with Archaeornithoides? Deltatheridium. 

    Funny story, on a voice call with the other devs, I brought up "Delta" and while me and Adamsaurus02 were looking at the teeth, I basically compared it to a stoat, killing anything, including larger animals like the cold blooded demon it is. And what do you know...

    Anyhow. Due to the fact that Deltatheridiids (and -oids)are absolutely, atrociously, terrible at preserving post crania material (I literally call them Floating Heads), reconstructing its body was a living hell. However, the fact that it was a basal METATHERIAN helped out a lot. I used Didelphis virginiana and Monodelphis domestica as references, along with the extinct metatherian, Sinodelphys. I used browns and peaches a lot to reflect it being a desert hunter, with black and white eye spots to scare off predators. The the eye stripe is similar to what Cheetahs have, helping reduce glare.

Nice to see a visually stunning mammal that still uses "drab" colors. :D

It looks very fierce! So even a smaller dinosaur would think twice before messing around with this one. ;)

So for the moment, what would be the largest animal in the game? Any chance of using Plesiohadros?

We currently have discussed Plesiohadros, but have decided that for now it will not be in the game. The largest in game animal will be Pinacosaurus. I'm currently reworking the size estimates and concept art. It is around 6 meters long (16 feet or so) from the largest known individuals. However I would not be surprised if it got slightly bigger.

Wouldn't the largest be that undescribed tyrannosaur?

It is said to resemble Tarbosaurus and Zhuchengtyrannus, so it would have gotten pretty big.

Also, 6 meters is 19.8 feet. The largest Pinacos are about 5 meters, which is about 16.4 feet.

Yeah woops, meant to say 5 there.

and due to the undescribed nature if the tyrannosaur, it is currently not in the game

If the incident you described truly was a predation event, then it was quite an impressive one. So just like today, animals were doing badass things.

Nah, no healing indications or natural distortions or fusions, just raw damage. Due to the placement of the bite, it's likely it tried to "Tackle" its prey. Lions and stoats are some of the few that use this strategy, mostly because their prey is much larger than themselves. The Delta probably was trying to subdue and suffocate its prey, leading to the puncture wound.

Apparently there is some indication of the troodontid having survived with a dismantled jaw for some time......

I've already seen that. And even after looking a second time, nowhere did I catch anything suggesting that the dinosaur lived with its injuries for some time. The two authors even state "predator or scavenger", which you could probably take to mean that they don't rule out the idea of this being a scavenging event.

I'm not ruling out predation, but I'm failing to see where "there is some indication of the troodontid having survived with a dismantled jaw for some time".

Ok, before people make an error. The animal without a doubt died. The wound shows know signs of healing. If the animal was scavenging, surely there would be bigger animals that would have swallowed it all. And if it did reach the carcass, there would be scratches and indentations everywhere, plus: nothing left (the animal is probably starving, anything will do). The missing cranium without a doubt occurred post-mortem.

Say, would it have eaten the poor troodontid on the spot or would it have dragged it away from other scavengers?
