Toxodon platensis - fragment of a molar tooth ...

Specimen number: NHMUK PV M 102046b

Specimen Link:

Taxon: Toxodon platensis

Description: Fragment of a molar tooth from the lower jaw (lingual enamel of right lower m3)

Site: Based on preservation, this probably came from Punta Alta, Buenos Aires Province, Argentina

Age: Late Pleistocene i.e., between 126,000 and 11,700 years old

Collection: Probably found between September and October 1832 or between August and September 1833 by Charles Darwin (specific date was not recorded)

Comments: This specimen has been associated with the other Darwin specimens in the collection since at least 1884 and is probably part of Darwin’s collection. This is almost certainly from the same tooth as NHMUK PV M 102046a.

Toxodon is an extinct herbivorous (plant eating) mammal from South America. It is often reconstructed to look like a cross between a hippopotamus and a rhinoceros, although it is not closely related to either. It was first described by Richard Owen based on specimens collected by Charles Darwin on the Voyage of the Beagle.
