Pristis is a genus of

critically endangered today.[4][5]

Taxonomy

The scientific genus name Pristis is derived from the Greek word for saw.[6]

Living species

Recent authorities recognize four species:[4][5][7][8]

These are divided into two

Anoxypristis cuspidata was formerly included in Pristis, but it has a number of distinctive features (for example, no teeth on the basal quarter of the saw) and recent authorities place it in its own genus.[3][5][7]

Extinct species

According to Fossilworks, extinct Pristis species only known from fossil remains include:[13]

Fossil rostal teeth of Pristis lathami from Khouribga (Morocco.)

However, among this list are some

Late Paleocene to the Quaternary period.[1][2] Fossils have been found all over the world.[13]
