👉 Desmelytrurus is a genus of extinct mammals from the Late Triassic period, which occurred around 259 million years ago. These creatures were small and had a short lifespan due to their lack of teeth and jaws that would have been necessary for efficient chewing and digestion. The exact number of species remains unknown, but it's estimated that there may have been about 10-30 species in this group during the Late Triassic period.
