Xilousuchus is an early triassic Pseudosuchian archosaur closely related to Arizonasaurus. Like Arizonasaurus, it had elongated neural spines, which likely formed a sail.

Summary

[edit]
This paleontological restoration is inaccurate, or its accuracy is disputed.

Reason: The prong-and-groove premaxilla-maxilla articulation is replaced with a flat margin. The braincase appears to be misinterpreted as fragments of the jugal and postorbital. The cervical ribs don't actually articulate onto the vertebral rib facets. The caudal vertebrae is shaded as if it preserves a complete neural spine (unlike in the fossil). The clavicle is misinterpreted as a scapula. Some of the other fossils aren't depicted at all (ungual, sacral vertebra, the other caudal vertebra).

English: Skeletal reconstruction of Xilousuchus sapingensis, proportions based on and adjusted from Arizonasaurus. Tail is longer to balance out the neck, sail was shrunk to match the neural spine length and curve.
