THE JANE DIARIES, ENTRY #28
December 8, 2014
3:23 pm: Starting on Larson (2013).
“In part due to the absence of additional specimens, the validity of Nanotyrannus came under question by various researchers, culminating in 1999 when Carr assigned the specimen to Tyrannosaurus rex. Carr presented a compelling argument…”
[Clarification: What I did was show that all of the differences between the Cleveland skull and adult T. rex are identical to the differences that are seen between juvenile and adult Albertosaurus libratus, and that it shares similarities with adult T. rex that are best explained by the small skull belonging to the same species, namely T. rex - the only tyrannosaurid in strata of the Late Maastrichtian of the American West.]
“Carr’s 1999 paper kindled a debate that has grown hotter by the year.”
[The scientific literature, as penned by actual scientists, does not show a debate beyond the dissenting view in Currie (2003). Carr et Williamson (2004) did not engage that article since it was submitted for publication - and possibly in press - by the time the 2003 article was published.]
3:40 pm: Stop.
