Epachthosaurus
Name:
Epachthosaurus
(Heavy lizard).
Phonetic: E-pak-foe-sore-us.
Named By: J. E. Powell - 1990.
Classification: Chordata, Reptilia, Dinosauria,
Saurischia, Sauropodomorpha, Sauropoda, Titanosauria,
Lithostrotia.
Species: E. sciuttoni
(type).
Diet: Herbivore.
Size: Up to ten meters long.
Known locations: Argentina, Chubut Province -
Bajo Barreal Formation.
Time period: Cenomaian/Turnonian of the Cretaceous.
Fossil representation: Remains of three
individuals, one of which is represented by an articulated and almost
complete partial post cranial specimen.
Epachthosaurus
is a genus of basal titanosaur
that lived in South America during the
late Cretaceous. This is significant because much more advanced
titanosaurs were living in South America at this time, which in
itself suggests that Epachthosaurus was a late
surviving form. One
individual of Epachthosaurus (UNPSJB-PV 920)
is represented by an
almost complete skeleton lacking only the skull and some of the
vertebrae, and is recognised as one of the most complete individual
titanosaurifom skeletons so far discovered.
Epachthosaurus
seems to have been quite small for its type of dinosaur, and living
in South America during the late Cretaceous, it may have been preyed
upon by abelisaurs,
and perhaps even
carcharodontosaurs.
