List of ursids

Over 100 extinct Ursidae species have been found, though due to ongoing research and discoveries the exact number and categorization is not fixed.

Ranges are based on the IUCN Red List for that species unless otherwise noted.

Ursus (American black / Asian black / brown / polar bear) Helarctos (sun bear) Melursus (sloth bear) Tremarctos (spectacled bear) Ailuropoda (giant panda) The following classification is based on the taxonomy described by Mammal Species of the World (2005), with augmentation by generally accepted proposals made since using molecular phylogenetic analysis; this includes the division of the giant panda into two subspecies.

There are several additional proposals which are disputed, such as reclassifying the subspecies of the brown bear into a smaller set of clades,[2][3] which are not included here.

23,000[25] [24] In addition to extant bears, a number of prehistoric species have been discovered and classified as a part of Ursidae.

Where available, the approximate time period the species was extant is given in millions of years before the present (Mya), also based on data from the Paleobiology Database.
