Last Dinosaur of 2011
_Acta Palaeontologica Polonica_ released it's final issue of the year, right at
the end of it. This issue contains one new dinosaurian taxon -- an
ornithischian -- and two discussions of other named dinosaurian taxa, one
sauropod and one ornithischian.
Farke et al. describe what is likely the official last dinosaur named for year
2011: *Spinops sternbergorum,* meaning that at least the date "2011" won't need
to be changed to "2012". It also means that *Spinops sternbergorum* caps out
the Year of the Ceratopsian and its plethora of new taxa. (Farke et al., pdf
supplemental info here:
Little mentioned, however, is the cranial osteology and ontogeny described for
*Saurolophus angustirostris* by Phil Bell (pdf here:
And of course, Denver Fowler and Bob Sullivan provide new remains attributed to
*Alamosaurus sanjuanensis* which project it at truly top-of-the-sauropod size.
I remain skeptical over assigning material not only with ontogenetic
differences of gross size and material composition from holotypes, especially
holotypes base don juveniles (or teeth). However, the work itself substantiates
a sauropodan-sized animal, and that's nothing to shake a brachiosaur at. (Pdf
Congrats for coming in at the end, and making it just barely before 2012.
Hopefully more stuff can be produced before it all ends in May!
