Sometimes, knowing when a dinosaur lived can be more informative than knowing how it looked or behaved. As early theropods go, Lophostropheus is fairly obscure; it seems to have been closely related to, and probably similar in appearance to, Liliensternus and Coelophysis. What makes this western European theropod important is that its bones were found in sediments dating to the Triassic/Jurassic boundary about 200 million years ago, a transitional period in dinosaur evolution that isn't very well represented in the fossil record.
