link Alcovasaurus longispinus so Roman Ulansky proposed that Stegosaurus longispinus should be a different genus from stegosaurus. he coined Natronasaurus longispinus and due to Ulansky self-publishing the name in an electronic publication (not archived by an independent organization and without an ISSN.) the name was rendered invalid and Alcovasaurus longispinus became the name. (wikipedia,dinochecker) so new north american stegosaur with huge tail spikes. Edited by Paleop, Mar 22 2016, 04:07 PM.

So this means that we now know of three large stegosaur genera from the late Jurassic of North America? Interesting.

Hesperosaurus wasn't really that big.

It would be very interesting to found out more about the stratigraphic position of those Stegosaurid genus. I kinda off doubt that all genus and species of Stegosaurids from Morrison coexisted at the same time and knowing when exactly they lived would help us understand how they changed and adapted through the changes in it's envioriment (just as it has been noticed in the evolution of Triceratops horridus to Triceratops prorsus). |

IIRC, Hesperosaurus was more basal than Stegosaurus, though I'm not entirely certain how it falls in line with Alcovasaurus. |

Interesting.... I wonder if it coexists with Stegosaurus or Hesperosaurus and how do their role in ecosystem function as the three genera are very similar and were actually thought to be the same for some periods. |

I've always figured A.longispinus might fit as a kentrosaur style stegosaur, though thats (currently) just wishful thinking |
