**Xenodontia** (lit. "strange/foreign teeth") is an invasive clade of platydonts that rafted to Crescentia.

## Description

The first xenodonts appeared on Crescentia via a rafting event, over fifty million years after the arrival of the notoformes. Like other basal platydonts, the first xenodonts were small arboreal animals, occupying niches inaccessible to the notoformes. However, they diversified and expanded (the two confirmed later lineages are the predatory streptotarsans and browsing brachiocephalians), with their superior physiology allowing them to overtake most of Crescentia's megafaunal niches.

The xenodonts went into a steep decline upon the arrival of the ice age; the majority of species could not survive the rapid climate change and subsequent ecological upheaval. The xenodonts did not retake their place as the dominant fauna after the ice age's end, having been supplanted by the eriotheres.
