Eucercosaurus (meaning "good-tailed lizard"[1]) is the name given to a genus of ornithopod dinosaur from the Albian stage of the Early Cretaceous. It was an ornithopod discovered in the Cambridge Greensand of England and is known from 19 centra, 3 sacrals, 4 dorsals and 12 caudals, and a neural arch found near Trumpington, Cambridgeshire.[1][2] The type species, E. tanyspondylus, was described by British paleontologist Harry Seeley in 1879.[3]

It is considered a dubious name, and was once considered an ankylosaur.[4] According to a 2020 study, Eucercosaurus and Syngonosaurus were basal iguanodontians.[5]

  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.
