Hallopus

Article summary

Hallopus is an extinct genus of small "sphenosuchian" crocodylomorph, known from the Late Jurassic Morrison Formation of North America. The only known species Hallopus victor was originally named in 1877 as a species of the dinosaur Nanosaurus, and was moved into its own genus by Othniel Charles Marsh in 1881. It was a quite small animal, reaching a length of 1 m (3.3ft) with long and slender limbs. Macelognathus, a similarly slender-proportioned crocodylomorph to Hallopus, may be synonymous with it.
