3 complete skulls, many partial skull and skull
elements, many partial and complete skeletons representing at least
60 individuals.
(AMNH 680) (9.7 m; 2.3 tons) dorsals 5-7, four proximal
caudal ertebrae, ilium, pubes, ischia, femur (1.008 m), tibiae,
fibulae, astragali, calcaneum, metatarsus, pedal phalanges (Chure,
2001) (AMNH 5767; holotype of Epanterias amplexus) (12.1 m; 4.5
tons) axis, sixth or seventh cervical centrum, first dorsal neural
arch, coracoid (328 mm long), distal metatarsal IV The largest
"traditional" Allosaurus specimen is AMNH 680, while the Epanterias
holotype is even larger. The fact a 12.1 meter specimen of a taxon
normally 7-9 meters exists just shows us how much variation can
uccur within a single species, and how little to trust any of our
specimens as being representative of their species.

Andres collection, MNHNUL/AND.001 Horizon: Lourinha Formation, Upper
Kimmeridgian-Tithonian, Late Jurassic.Material: Part of the right
quadrage, several vertebrae and chevrons, several dorsal ribs, and
gastralia, a partial pelvis, parts of the hind limbs and several
indeterminate fragments.
The holotype cannot be identified as A. fragilis or A. sp.
nov., although it is definitely Allosaurus. The nearly complete
specimen USNM 4734 is designated the topotype, as it comes from the
same quarry as the holotype. |
