Jul 17, 2024 · The remaining groups of theropods comprise the Avetheropoda ("bird theropods") (sometimes "Neotetanurae", or "new tetanurines"). Avetheropods share the following transformations from the ancestral tetanurine condition:

Carnosauria was originally used as a general term for all of the big theropods, including the elusive and quite possibly non-existent, Megalosaurus, the Snark of dinosaurs.
