Ceratosauria
.
ERA: Late
Triassic
(
Norian
220.7 - 209.6
Ma
).
SIZE: Length 3 m (10 ft).
LOCATION:
North America
.
FOSSILS: Two
dorsal
vertebrae
and four partial
caudal
vertebrae
, partial
scapulocoracoid
,
pubis
, partial
ischium
,
ilium
fragment, partial
femora
, partial
tibia
,
metatarsals
,
phalanges
. A complete right
pubis
originally referred to Coelophysis longicollis is also now referred to Eucoelophysis.
COMMENTS: Eucoelophysis was a ceratosaur distinguished from
other ceratosaurs by characteristics of the
pubis
and
femur
. It was originally discovered in 1993 and known as the “Orphan Mesa theropod”. It
was much smaller and delicate than either Ceratosaurus or Dilophosaurus,
and more closely resembled Coleophysis and Syntarsus. The lack of a skull
makes it difficult to characterise beyond Ceratosauria.
