How did this one get out?? I must have mentioned it casually to somebody in 
an email or sent it as part of my Mesozoic Meanderings #2 manuscript, and now 
it's posted on the Web. Sheesh. Well, I intended to rename the genus for 
Procerosaurus exogirarum (formerly Iguanodon exogirarum) because 
Procerosaurus Fritsch 1905 is preoccupied by Procerosaurus Huene 1902, and a 
few years ago Ben Creisler came up with the replacement name Ponerosteus, 
which means "bad bone" or "poor bone." This fully describes the type specimen 
of Procerosaurus exogirarum, which is so indeterminate that I can barely 
classify it as Ornithischia incertae sedis. Also, the species name derives 
from the genus Exogyra, a shell from the formation in which the "bad bone" 
was discovered, so the species epithet should be spelled "exogyrarum" (as it 
has been several times in the literature already). As far as I know, 
Ponerosteus hasn't appeared in print yet, and it shouldn't until I publish it
