The paleobiogeography of the theropod clade Compsognathidae is here
reaccessed in order to test the hypothesis of this taxon being adapted
specifically to inhabit semi-arid environments. Data about localities
where these fossils were collected and their paleoenvironments were
gathered from the literature. Compsognathids seem to be found
especially in sedimentary deposits known as Fossil Lagerstätten, which
were formed under a set of specific conditions that allowed the
preservation of the fragile bone remains of these animals. This bias
limits an accurate analysis of the historical and/or ecological
paleobiogeography of this taxon. Actually, it is possible that
compsognathids had an almost worldwide distribution during the
Mesozoic Era. Their occurrence in Lower Cretaceous rocks of China
suggests that they also inhabited environments with moist conditions
instead of being restricted to semi-arid to arid environments.
