The
full type species name for this dinosaur is Lepidus praecisio
which
means ‘fascinating fragment’. This is because while not many
fossils of this dinosaur are known, we can observe that the
astragalus (talos) and calcaneum are fused into one, which is a
trait of neotheropod dinosaurs. At the same time however, the tibia
shows a similarity to more primitive theropod dinosaur forms such as
Herrerasaurus.
Living
in what is now the USA during the Triassic, it is possible that
Lepidus lived ina same ecosystems as dinosaurs such
as Coelophysis
and
Tawa.
