Belosaepiidae is an extinct family of cephalopods known from the Eocene epoch, and bearing close similarity to the sepiid cuttlefish, whilst retaining the remnants of a belemnite-like guard.[2][3] It is thought that this species was most common for its time.[4]
Seagrass Importance To Belosaepiidae[edit]
A faunal collection has been found that contains Belosaepiidae and Sepiidae, suggesting that they are likely to have originated from a seagrass environment in the past. As there was a lack of seagrass overtime in the North Atlantic during the late Eocene period, a particular species called belosaepiid went extinct within the family belosipiidae.[5]

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.
