Stem-Bird Files: Kayenta Lindwyrm

Theropoda>Neotheropoda>Dilophosauridae>Dilophosaurus>D.wetherilii
Welles, 1954
Time: Sinemurian (193 million years ago)
Length: Up to 6.5 meters (21.3ft) when fully grown.
Height: Up to 1.5 meters (4.9ft) at the hips when fully grown.
Weight: Up to 350kg (0.35 tonnes).
Habitat: The Kayenta Formation of Arizona, U.S, North America.
Ecology and hunting habits: Small to medium-sized terrestrial predator. With teeth that are very long, but thin in cross-section, a notch in the upper jaw and reported swimming tracks in several localities, it's likely that Dilophosaurus was at least partially piscivorous, like the convergently similar spinosaurids. The shape and flexibility of its jaws may not have allowed it to prey on animals as large or larger than itself, and it most likely hunted smaller prey, like the majority of theropods.
Diet: Early sauropodomorphs such as Sarahsaurus, the ornithischians Scutellosaurus and Scelidosaurus, early crocodylomorphs, the cynodont Olygokyphus, and the pterosaur Rhamphinion, as well as bony and lunged fish.
Competition: Juvenile Dilophosaurus would have competed for prey with smaller theropods Coelophysis and Kayentavenator and primitive crocodylomorphs. Adults were most likely the apex predator of the Kayenta, with no competition other than eachother.

The terrifyingly cute, venomous Frilled Lizardilo... wait, wrong universe. What is it with semiaquatic lifestyles these days that everyone's getting into them? Pfft, newbies.

Update 06/29/17:
-Lineart completely remade.
-Replaced human scale figure.
-More accurate size estimate, now along the centra as is the norm, instead of in a straight line.
-Removed ''average adult'' estimates, they're dumb.
-Minor text corrections.

Based on skeletal reconstruction by , with minor changes to match UCMP 77270's proportions.
