Not the case. Triceratops and Torosaurus had been considered separate geneses, but recently it has been thought that the Triceratops could be the juvenile forms of the Torosaurus. Though Torosaurus may be the mature form, the name Triceratops was given first, and historic precedence is recognized. Triceratops remains, and some museums are phasing out the Torosaurus name. This theory is still controversial, and has not yet been generally accepted.
