Welcome to the blog that concerns all dinosaurs that are more closely related to (and including) Tyrannosaurus rex than to the English sparrow (Passer domesticus). This will be the place to read about tyrannosauroid osteology, ontogeny, and phylogeny, as well as updates on my tyrannosauroid research as it happens, my thoughts about new scientific discoveries on tyrannosauroids, and the occurrences of tyrannosauroids in pop culture.

THE JANE DIARIES, ENTRY #22
Framed and mounted, but the Science isn't done.
November 27, 2014
~1:00 pm: resumed adding characters from Carr (1999).
1:25: At the jugal in the Taxonomic Differences section.
This section has been misunderstood in the literature (e.g., Currie, 2003) and at the time I
should have recognized that possibility and made repair; it would have been a straightforward
correction to make.
1:47: Just reached the postorbital of Carr (1999)! Brief
1:55: Back to work!
2:41: Reached the braincase section of the Taxonomic Differences
section; I need a short break.
2:52: For some reason I am stymied with what to do with the
braincase section – this structure is entirely missing from Jane, but it is
entirely present in the Cleveland skull and in adults. Do I contrast the
Cleveland skull from them? That does make the most sense, as long as it is not
redundant with Carr (1999) or W&R (2009, 2010).
3:01: Hunger is tearing at me; I must eat something now.
3:13: Back to work!
3:37: Time to wrap up.
