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. This shark is a transitional species, showing intermediate features between the extant great white shark and the fossil white shark, C. hastalis.[2][3][4] C. hubbelli appears to be geographically restricted to the Pacific Ocean, with fossils of C. hubbelli recovered from Peru,[4] Chile[citation needed], California,[5] and New Zealand.[6] This exclusive distribution suggests a Pacific origin for the great white shark.

This shark was named in honor of Dr. Gordon Hubbell (the scientist who recovered the specimen from a farmer who found it in 1988)[7] in recognition of his contribution to shark paleontology and for donating the specimen to the Florida Museum of Natural History in 2009.[8][3][6] It was about the size of the modern great white shark, reaching 4.9–5.1 metres (16–17 ft) long.[3][9] Its growth curve shows that it grew at a slower rate than the modern great white shark.[3]
