The other T. rex is a beetleSourced
A fossil called T. rex was found. It was a beetle, not a dinosaur.
A beetle preserved in Dominican amber was named Tyrannasorus rex in 2001, deliberately echoing Tyrannosaurus rex. The fossil dates to the Miocene. Both species can be abbreviated T. rex, although one is a small insect and the other a famous dinosaur.
The abbreviation hides quite a size difference.
