Dromomeron

Dromomeron (meaning "running femur") is a genus of lagerpetid avemetatarsalian which lived around 220 to 211.9 ± 0.7 million years ago.

[3] However, noting prominent differences between their femurs which cannot be attributed to variation with age, Rodrigo Muller rejected this proposal in 2017.

[2] Dromomeron and type species D. romeri are based on GR 218, a complete left thigh bone from the Hayden Quarry at Ghost Ranch, New Mexico.

[5] Other specimens from the Chinle Formation of Arizona and a roughly contemporaneous part of the Dockum Group of Texas also have been assigned to this genus.

[5] A third species, D. gigas, was described by Martínez et al. (2016) on the basis of fossils recovered from the Norian Quebrada del Barro Formation in northwestern Argentina.
