The remarkable thing about Neovenator
MIWG6348 is the shape of the skull profile: this has been described as
'puffin-like'. The naris is huge. The teeth have very much slipped out
of their sockets. Neovenator was certainly the major flesh-eater around in the UK at this time. The pleurocoels continue troughout the dorsal column.
Experts have confirmed that Neovenator is a previously unknown species, distantly related to the Allosaurus
from North America but lighter and quicker. The fossilised bones were
first found in 1978 but scientists had only recently dug them all out.
Hutt was delighted to find such a complete skeleton. Neovenator has five premaxillary teeth (as does Allosaurus, but not Sinraptor or any other carnosaur).
is rather complete approx. 70% of the skeleton is known. It has
avetheropodan characters (e.g. large pubic boot) and is assigned to the
Allosauroidea Sereno et al. ,
1994, on the basis of a nasal that participates in the antorbital
fossa.Left metatarsals II and IV are there, as is a complete phalangeal
set for met IV. Three pedal unguals have been found, the largest of
which has an odd shallow grove along the dorsal surface.
Naish et al..(2001) distinguish Neovenator from
other theropods based on the shape of the raised crests of the nasals
(not known at the time of description) and a dorsal groove on at least
one of the pedal ungual phalanges. Additionally, Neovenator possesses
premaxillae with a ridge- and groove structure on their medial
surfaces, a condition not yet reported in other theropods.
Holtz (1998) found Neovenator to be the sister taxon of Allosaurus, while Naish et al. (2001) speculated that is was carcharodontosaurid. Although the original material suggests that Neovenator reached a length of 7 meter, isolated remains indicate individuals as long as 10 meter.
