Stylidens is an extinct genus of mammaliaforms, possibly belonging to Morganucodonta, that lived in what is now England during the Middle Jurassic. Its type species is Stylidens hookeri, which was named in 2016 by Percy M. Butler and Denise Sigogneau-Russell from an isolated lower molar found at the Forest Marble Formation. A second molar referable to the genus is also known, which may represent a separate species.[1]
Etymology
[edit]The generic epithet Stylidens is derived from the Latin words stylus, alluding to the pointed cusps of its molars, and dens, meaning "tooth". The specific name hookeri honours the British researcher Jerry Hooker.[1]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
