a very fuzzy herrerasaurus

I know this meme is overplayed at this point, but I was looking at archosaurs on Wikipedia again and my brain automatically did this.

Silesaurus opolensis here was a type of dinosauriform – a reptile very closely related to the ancestors of true dinosaurs, but not quite actually a dinosaur itself.

Living in Poland during the Late Triassic (~230 million years ago), it was a quadrupedal animal roughly the size of a large modern dog, about 50cm tall at the shoulder (1'8") and 2m long (6'6"). The front of its lower jaw was toothless and covered with a keratinous beak, and there may have been a corresponding much smaller beak at the very tip of its upper jaw, too.

It was originally thought to be a herbivore, but coprolites full of insect remains suggest it was probably more of an omnivore, possibly foraging by pecking in a convergently similar manner to its distant bird cousins.

In fact, one of those pieces of Silesaurus poop was recently found to preserve a new species of tiny beetle in incredible detail.

A family of Venetoraptor gassenae decide to take a shortcut via Prestosuchus to their favorite tree. What should have been a swift trick turns to peril as the youngster misplaces his, otherwise, impressive leap.

I suppose Avemetatarsalia would be communism

but dinosauromorphs socialism?
