Carcharodon hubbelli, also known as Hubbell's white shark, is an extinct species of white shark that evolved between 8 and 5 million years ago during the Late Miocene to Early Pliocene epochs. The shark is a transitional species, showing intermediate features between present-day great white sharks and smaller, prehistoric mako sharks.[2][3][4] Its fossils have been unearthed in New Zealand and Peru.[5]

This shark was named in honour of Gordon Hubbell (the scientist who recovered the specimen from a farmer who found it in 1988)[6] in recognition of his contribution to shark palaeontology and for donating the specimen to the Florida Museum of Natural History in 2009.[7][3][8]
