Megachasma applegatei
Megachasma applegatei is an extinct species of Megamouth shark from the Oligocene to early Miocene (28-23 Mya) of the Western United States.[1][2] The type fossil was discovered in the San Joaquin Valley in 1973, but only described in 2014, when the species was named after its discoverer, Shelton Applegate.[3]

Description
M. applegatei was described from a single tooth. Based on comparison with the teeth of the recent species (Megachasma pelagios), it was approximately 6 m long and, like modern megamouth sharks, probably fed on fish and small planktonic invertebrates both in deep and shallow water habitats. Its teeth had shorter crowns and a pair of side cusplets.[4]
