Pristis lathami – Saw Fish Peg
Species Name: Pristis lathami
Age: Eocene, Bracklesham Beds, 55 to 33 Mya.
Location: Lee on Solent, Hampshire
Pristis lathami Sawfish peg collected from the Eocene Bracklesham Beds in Lee on Solent, Hampshire. Pristis is a genus of Sawfish of the family Pristae. Sawfish are characterised by having a long extended nose or rostrum which resembles a saw. The rostrum is lined with peg like rostral teeth and it is generally accepted that the rostrum is used to strike prey items rendering them incapacitated. The Bracklesham beds in which these pegs were found are well known among paleontologists and fossil collectors in Britain; they have yielded over 160 different species of fish and the beds continue to be productive today despite having been pillaged by collectors for over 100 years. These peg like teeth measure approximately 20 - 30 mm and are supplied in small plastic bags with an information label.
