Paritatodon is an extinct mammaliaform which existed in Kyrgyzstan and England during the Jurassic period.[1] It was originally the holotype specimen of Shuotherium kermacki, but Martin and Averianov (2010)[1] argued that it resembled the genus Itatodon (Docodonta) and so renamed it Paritatodon.
Nonetheless, some recent phylogenetic studies assign it (and Itatodon) to Shuotheriidae,[2] while others continue to consider the taxon a docodont.
Like many Mesozoic mammals, this species is only known from its teeth, in this case two lower molars from the Forest Marble Formation in England,[3] and a single left lower molar from the Balabansai Formation in the Fergana Depression, Kyrgyzstan.[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.
