Using 03-mini-high + Search I get the right answer he was looking for:

  The species was first split at the subgeneric level by Gregory S. Paul in 1988—he proposed the name Brachiosaurus (Giraffatitan) brancai. Then in 1991 George Olshevsky raised the subgenus Giraffatitan to full generic status, so that B. brancai became Giraffatitan brancai. Later, a 2009 study by Michael P. Taylor provided detailed evidence supporting this separation.

I guess Mike Taylor will gracefully cede his point now?

It is very funny to me that someone would feel the need to complain about a niche factual error in pretrained LLMs without even enabling RAG. If you even know the basics about this field, you shouldn't be surprised.

Of course this was probably more about ego stroking his paleontological achievement than a thoughtful evaluation of the current state of LLMs.
