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]
gollark: Relatedly, apparently GPS can reach sub-metre accuracy now, which is very impressive.
gollark: You would have to detect and correct for it.
gollark: Weird turbulence stuff could happen though?
gollark: I figure that with good acceleration/rotation data, knowledge of initial velocity and stuff (GPS should work when it's out of the atmosphere, right?), and rough knowledge of what the trajectory is you could get it to somewhat work.
gollark: It's possible that people just didn't want space killsats for some reason? I can't see why, but maybe.
