Ankylosaurs

[gmbra@cygnus.uwa.edu.au]

Much of what you want to know can be found in "Review of Lower and Middle
Cretaceous Ankylosaurs of North America" by Carpenter and Kirkland in Lower
and Middle Cretaceous terrestrial ecosystems, New Mexico Mus. Bull No 14,
p249 (1998). Its available from the New Mexico Museum of Nat Hist (pre -pub
price was US$40) - the publication is well worth the money, as it has about
300 pages almost entirely devoted to dinosaurs, including 5-6 newly
described critters.

>>>I made up a list of ankylosaurians I thought may be congeneric or
conspecific, and was wondering if anyone has any comments about them
(yeah, I know some of these are nomen dubia):

>>>     1. *Amtosaurus magnus*, *Maleevus disparoserratus*, and
*Talarurus plicatospineus* (also, does anyone know if *A. magnus*'s
identity as a ankylosaurid or hadrosaurid has been confirmed?)

        2. *Sauropelta edwardsorum* and *Priconodon crassus*

        3. *Pawpawsaurus campbelli* and *Texasetes pleurohalio*

        4. *Shamosaurus scutatus* and *Sauroplites scutiger*

        5. *Nodosaurus textilis* and *Stegopelta landerensis* (usually
considered  conspecific)

        6. *Tsagantegia longicranialis*, *Shanxia tianzhenensis*, and
*Tianzhenosaurus youngi*
        
        Also, is there anything new on *Dyoplosaurus acutosquameus*
versus *Euoplocephalus tutus*, like being two genera, two species of
>>>>*Euo*., or one species?     -*Thescelosaurus*
