Re: [dinosaur] Procheneosaurus

[Tyler Greenfield <tgreenfield999@gmail.com>]

The conserved genusÂProcheneosaurus Matthew, 1920 has priority over Lambeosaurus Parks, 1923 if the two genera are considered synonymous. However, the subsequently designated type species of Procheneosaurus, Tetragonosaurus praeceps Parks, 1931, does not have priority over the type species of Lambeosaurus, Lambeosaurus lambei Parks, 1923. If the two species are considered synonymous, the correct combination would be Procheneosaurus lambei (Parks, 1923).

Presumably because the type species of Procheneosaurus (Tetragonosaurus praeceps) was not named until eight years after Lambeosaurus lambei.

It's an officially conserved name and it's older than Lambeosaurus, so why isn't it used?
