Xunmenglong (from Chinese: 迅猛龍/迅猛龙; pinyin: Xùnměnglóng; lit. 'swift fierce dragon') is a genus of compsognathid theropod dinosaur from the Huajiying Formation from Hebei Province in China. The type and only species is Xunmenglong yinliangis. The holotype material consists of a pelvis, tail base and hindlimbs that had previously been part of a chimera containing three different animals. The animal is described as being the smallest known member of Compsognathidae, being about the size of the sub-adult Scipionyx holotype specimen or approximately 0.5 meters (1.6 feet) in length.[1]
Classification
[edit]In the original description, Xunmenglong is recovered as a Compsognathid in a polyomy including Compsognathus, Huaxiagnathus, and Juravenator. However, Andrea Cau (2024) recovered Xunmenglong not as a Compsognathid, but instead as a basal member of Tetanurae.[2]

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.
