Paratrigodon fossil map
Where fossils of Paratrigodon have been found, shown on the Earth as it looked about 5 million years ago and on today’s map.
Dots are fossil collections recorded in the Paleobiology Database. The “then” view moves today’s fossil sites back to their positions 5 million years ago (the time slice nearest the median age of the fossils) using the Merdith et al. (2021) plate model; positions are approximate. Open on the timeline map →

About Paratrigodon
Paratrigodon is an extinct genus notoungulate belonging to the subfamily Toxodontinae, containing one species, P. euguii. Like its close relative Trigodon, it is known for the presence of a horn-like protuberance on its forehead. Fossils of Paratrigodon are known from the Arroyo Chasicó Formation dating from the Chasicoan period, and teeth from the Laventan-aged Quebrada Honda Fauna of Bolivia were also associated with the genus, although considered too different from the type species to be assigned to it.
