Lagosuchus

Lagosuchus was a small archosaur from the Middle Triassic period. It is generally thought to be closely related to dinosaurs, as a member of the Dinosauromorpha.

Lagosuchus was a lightly-built archosaur, and is notable for its long slender legs and well-developed feet - features it shares with certain dinosaurs. These features, along with the shape of its hips, suggest that it could run on its hind legs for short periods, although it probably moved on all fours most of the time. Lagosuchus was likely an agile predator that could use speed to chase its prey and to escape larger predators.

Lagosuchus is regarded by some to be nomen dubium and L. lilloensis has been referred to Marasuchus by Paul Sereno in 1994.
