Likely Toxodon - fragment of lower jaw with ...

Specimen number: NHMUK PV M 102041

Specimen Link:

Taxon: Unknown but probably Toxodon

Description: Fragment of lower jaw with matrix attached

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 was associated in the collection with one of the lower jaws of Toxodon found at Punta Alta (specimen number NHMUK PV M 16566) and the preservation is very similar. It is possible it is part of the same specimen as the lower jaw, although there is no obvious join between the two.

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.
