Comments on T?. megagracilis

My second examination of t

almost fully grown.

Alternately megagracilis is a distinct species. If so, it is probably a
species of Tyrannosaurus, the specimen is too poorly preserved to be sure.
Rather like the leopard is in the same genus as the lions and tigers it lives
