The article begins with

"Trechnotheria is an extinct family of actively mobile mammal, endemic to what would be Asia and Africa during the Jurassic through Cretaceous periods from 161.2—99.6 mya, existing for approximately 61.6 million years.[1]"

This is the stratigraphic range given by the Paleobiology database, as stated in the source, but doesn't jibe with the definition of the taxon in the same article. Since Trechnotheria includes the therian mammals, its range should extend to the present day. Did the name Trechnotheria have a different historic usage? It only seems to date to 1975.
