Late Cretaceous
The Cenomanian (early Late Cretaceous) marine bird Pasquiaornis tankei (Tokaryk, Cumbaa and Storer, 1997) from Carrot River, Saskatchewan, Canada was named in Tanke's honor. Another fossil species named after him is the Late Cretaceous louse Cretolepinotus tankei found in amber. He also discovered the type specimen of the Late Cretaceous pachycephalosaurid dinosaur Texacephale langstoni.
