For the first time, scientists have documented an unusual defense: Some species of arachnids build giant doppelgängers on their webs, creating a frightening deception that scares off would-be killers. https://scim.ag/487Myn0

The name Bakiribu waridza derives from Kariri words: bakiribú (“comb”) and waridzá (“mouth”), referring to the animal’s comb-like dentition. The name also honors the Indigenous peoples native to the Araripe region, Brazil.

In the early Permian, a little less than 300 million years ago, life on land had long been rich and diverse, but most of the animals were still a bit... goofy.
Here's Eryops chasing down a Platyhystrix in a lush riverside forest in what is now Texas, some 290 million years ago.

The Dinosaur Park formation preserves the remnants of a large river system (more than 100 m wide) that once flew into the WIS. I imagine this piece to take place in the mid portion where the river meanders a lot. One would expect lots of sidearms and oxbow lakes to form here.

This kind of blew up on Twitter where tons of people apparently didn't understand what I was going for. This meme I shared here is not my own and it is wrong. Don't do this with sauropods. BUT I think it's absolutely valid to put soft tissue on marine reptiles that maximizes how streamlined they are
