Six paratypes were also designated: CMM-V-3876, a heavily worn tooth found at the beaches at the Flag Ponds Nature Park that was reworked from either the Choptank Formation or the Plum Point Member of the Calvert Formation; CMM-V-3981, a right upper lateral tooth collected from the beaches near Parkers Creek; CMM-V-4242, a tooth from the beaches of Calvert County, Maryland; CMM-V-5823, a left lower lateral tooth and the tooth that Palatas donated, which he found in the downstream of the May River, South Carolina; USNM 411148, a tooth also found in Bed 12 of the Calvert Formation cliffs near Parkers Creek; and USNM 639783, a tooth also collected from the beaches near Parkers Creek. They are large, measuring up to an excess of 4 centimetres (2 in) in height and suggesting a shark that grew to similar sizes or was larger than the modern great white shark,[3] which grows between 3.3–4.8 metres (11–16 ft) on average[4] and up to 6.6 metres (22 ft) in maximum length. The A. palatasi dental structure is heterodontic, meaning that the shape of teeth differs between each tooth in a jaw. Being warm blooded allows them …

Threshers also use their tail as a propeller, which they use to jump out of the water, as very few species of sharks do.

There are three species of thresher sharks: the common thresher (Alopias vulpinus), pelagic thresher (Alopias pelagicus), and the bigeye thresher (Alopias superciliosus). As of today, there is only one ever recorded attack on a diver.

The largest species is the common thresher, followed by the bigeye thresher, which gets its name from its unusually large eyes. The pelagic thresher occurs in the tropical and subtropical waters of the Indian and Pacific Oceans, usually far from shore, but occasionally entering coastal habitats.

In total, there are three species of thresher sharks: The common thresher (Alopias vulpinus), pelagic thresher (Alopias pelagicus) and the bigeye thresher (Alopias superciliosus).
