Teratophoneus

Teratophoneus

Thescelosaurus

Diet: Herbivore.Size: Between‭ ‬2.5‭ ‬and‭ ‬4‭ ‬meters,‭ ‬depending upon individuals/species.‭ ‬A particularly large specimen attributed to T.‭ ‬garbanii has been identified as being‭ ‬4.5‭ ‬meters long.Time Period: Maastrichtian of the Cretaceous.

Tianchisaurus

Diet: Herbivore.Size: Unavailable.Time Period: Mid Jurassic.

Diet: Herbivore.Size: Estimated about‭ ‬12‭ ‬meters long.Time Period: Late Jurassic.

Timurlengia

Diet: Carnivore.Size: Roughly estimated at about‭ ‬3.5‭ ‬meter long for the holotype,‭ ‬but this is possibly of a sub adult,‭ ‬and does not reflect the true adult size of the genus.Time Period: Turonian of the Cretaceous.

Titanoceratops

Diet: Herbivore.Size: Skull estimated about 2.4-2.6 meters long.Time Period: Campanian of the Cretaceous.

Titanosaurus

Diet: Herbivore.Size: Uncertain,‭ ‬but original remains first described for the genus seems seem to have come from an individual titanosaur about‭ ‬9-12‭ ‬meters long.Time Period: Maastrichtian of the Cretaceous.

Diet: Herbivore.Size: Roughly estimated to be about‭ ‬8‭ ‬meters long.Time Period: Late Cretaceous.

Tochisaurus

Diet: Carnivore.Size: Metatarsus‭ ‬24.2‭ ‬centimetres long.‭ ‬Second metatarsal‭ ‬22.2‭ ‬centimetres long.‭ ‬Precise body length unknown.Time Period: Campanian of the Cretaceous.
