Tyrannosaurus, and now Acrocanthosaurus, can be restored to a very high
level of accuracy, since all/most of their skeletal anatomy is known. The
skull of Giganotosaurus is well enough known for a very decent restoration,
and new material from the postcranium means that much of the rest of the
body will soon be better known.
Carcharodontosaurus and Spinosaurus are known only from relatively
fragmentary materials. The former can be modelled off other theropods, so a
restoration might be pretty close to accurate. Spinosaurus is necessarily
less accurate, since relatively little of its skeleton is known. Saurian
Studios does an excellent job given the data they have accessible:
unfortunately, there remains a lot of missing data with regards to
Spinosaurus and other spinosaurids.
Epanterias... Well, given the taxonomic confusion involved with this
beastie (is it Camarasaurus? Is it Allosaurus? Is it Saurphaganax?), there
is little we can say about this name. The giant allosaurid of the Morrison
(for which "Saurophaganax" looks to be the proper name) is pretty well
known, but I don't know if the skull has been recovered yet. Since a lot of
the most distinctive features within groups of large theropods are different
patterns of cranial ornaments, there is a good chance that whatever Saurian
picked for the skull may prove incorrect. Still, it would be better than
having a headless model!!
