Is Jane transitional between these morphological extremes? Is the variation hierarchical or disjunct? I'm in the process of finding out! Image is modified from Carr (1999).

1:37: Back to adding characters from Carr (1999), picking up from the Taxonomic Differences section with the surangular bone.
2:10: Done with the surangular and angular; the prearticular is next.
2:22: Dammit – MW just crashed again and this time I did lose a few lines of text…maddening.
2:46: Rule of thumb: include characters from Carr (1999) that have not been reported in BMR P2002.4.1.
3:04: Done with the Taxonomic Variation section; now at the Tyrannosaurid Taxonomy section. Next up is the list of juvenile characters that I listed for the Cleveland skull; the following step is to see if Jane is intermediate in condition between it and adult T. rex.
3:11: I need to take a brief break.
