I think the dinosaur *Protorosaurus* you're describing is an old name
for *Chasmosaurus*. *Protorosaurus* was the first new generic name
Lambe wanted to use for what is now called *Chasmosaurus*. He originally
described what would become the type species *C. belli* as *Monoclonius
belli*, back in 1902, but then renamed it when it became clear "M. belli"
was not *Monoclonius*. So, he coined the name *Protorosaurus belli* in
1914, the name coming from his belief that it was the ancestor of
*Torosaurus*. So far, so good. Then, it turned out *Protorosaurus* was
already in use, so he had to rename it, choosing *Chasmosaurus* later in
It is not legal for a generic name to be used twice. This does happen
on occasion accidently, though, necessitating a name change for the
younger claimant to it. *Camptosaurus*, for example, started out as
*Camptonotus*, which was already in use ("Aha," said the Inspector, "a
case of Preoccupation!"), necessitating the new name. *Anchisaurus* had
an even worse time of it. It took three tries to give it a name not
already in use.
"Augustia", the sauropod impersonating a stegosaurian, is a recent

will need a new generic name.
So, there's the twisted story of a ceratopid and its many
