Titanohyrax is an extinct genus of large to very large hyrax from the Eocene and Oligocene. Specimens have been discovered in modern-day Algeria, Tunisia, Egypt and Libya. Some species, like T. ultimus, are estimated to be as large as the modern rhinoceros. Titanohyrax species are still poorly known due to their rarity in the fossil record. Titanohyrax is unusual among the numerous Paleogene hyracoids by its lophoselenodont teeth (having teeth that are lophodont and selenodont), fully molariform premolars, and relatively high-crowned cheek teeth. This suggests the genus had a folivorous diet. The genus was first described by in 1922 for the species T. ultimus from the early Oligocene of the…

The largest prehistoric animals include both vertebrate and invertebrate species. Many of them are described below, along with their typical range of size (for the general dates of extinction, see the link to each). Many species mentioned might not actually be the largest representative of their clade due to the incompleteness of the fossil record and many of the sizes given are merely estimates since no complete specimen have been found. Their body mass, especially, is largely conjecture because soft tissue was rarely fossilized. Generally, the size of extinct species was subject to energetic and biomechanical constraints.
