Jeholodentidae

Fossil specimen of Jeholodens jenkinsi, National Museum of Nature and Science, Tokyo

The family Jeholodentidae is a possible eutriconodont family that was present in China around 125 million years ago during the time of the dinosaurs. There are currently two genera assigned to the family, Yanoconodon and Jeholodens.^[1][2]

However, recent studies have shown it to be paraphyletic in relation to Triconodontidae, with Yanoconodon being closer to them than to Jeholodens.^[3]

Jeholodentidae es una familia de triconodontos que vivió hace unos 125 millones de años en lo que ahora es China. Actualmente hay dos géneros asignados a esta familia, Yanoconodon y Jeholodens; se trata de pequeños insectívoros, con apariencia similar a los actuales coatíes y mapaches producto de la evolución convergente.
