New question! How did the bottlenose dolphin get "truncatus" as part of its name?

Well, partly from Latin "truncare" which means "to cut off" supposedly refering to their rostrum and face...

I also thought it has another reference, like a regional thing or location where the species might have first been discovered/seen

Not quite... it's sort of a misnomer, if that helps.

Okay, here's the answer.

In 1821 a bottlenose dolphin was captured in England. The animal was studied by George Montagu, who was surprised to find out that the animal had very flat teeth. (I guess this individual had worn theirs down quite a bit on something or other.) Because the teeth were "truncated" compared to observations of other types of dolphins, he named the species Delphinus truncatus. It was changed to Tursiops truncatus in 1855.
