Although a thresher shark, scientists hypothesized that A. palatasi may have looked similar to the great white shark.. A. palatasi is only known from isolated teeth. 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 ...
Galeocerdo mayumbensis is an extinct species of sharks that lived in the Miocene period. [1] A relative of the tiger shark (Galeocerdo cuvier), it lived in North America, South America, mainland Africa and Madagascar. [2] The teeth of G. mayumbensis are different from those of G. aduncus.
Squalodon is an extinct genus of whales of the Oligocene and Miocene epochs, belonging to the family Squalodontidae. Named by Jean-Pierre Sylvestre de Grateloup in 1840, [1] it was originally believed to be an iguanodontid dinosaur but has since been reclassified. The name Squalodon comes from Squalus, a genus of shark. As a result, its name ...
Alopias grandis is a species of giant thresher shark from the Miocene. Estimates calculated from teeth comparisons suggest the living animal was comparable in size to the extant great white shark. [3] Remains generally consist of teeth, which have been found in the United States in the Calvert Formation of Virginia and Maryland, [4] and in ...
The really dark shark teeth, Dunn said, are millions of years old and more commonly found. The lighter teeth, beige or pearly in color, fell out more recently. Eventually, once they’ve broken ...

Otodus megalodon teeth are the largest of any shark, extinct or living, and are among the most sought after types of shark teeth in the world. This shark lived during the late Oligocene epoch and Neogene period, about 28 to 1.5 million years ago, and ranged to a maximum length of 60 ft. [ 13 ] The smallest teeth are only 1.2 cm (0.5 in) in ...
Hemipristis serra is an extinct species of weasel shark which existed during the Miocene epoch. It was described by Louis Agassiz in 1843. [ 1 ] While today's snaggletooth shark is not very large or dangerous, Hemipristis serra , which lived in the Atlantic Ocean during the Oligocene and Miocene, was considerably larger than its modern-day ...
