an articulation surface direction of acquired three-dimensional information on the tooth T including information on a root canal R inside the tooth T two-dimensionally displayed to a prescribed surface in the articulation surface direction are displayed in a monitor 15 in association with each other....
so x-rays are used to produce radiographs (“radio” – x-radiation; “graph” – picture), images of the structures through which they pass. X-rays are used for medical evaluation because of their unique ability to pass
with no sign of the root resorption that would have preceded shedding of the tooth, so they were evidently going to be used for a while yet,probably a few months at least— BUT see the very useful comment from Jens Kosch below on the likely rapidity of tooth replacement inCamarasaurus....
Speaking of comparisons, here’s megalodon to remind everyone who’s boss. There’s no scale bar here, but the cast great white tooth is 65mm from the tip of the crown to the tip of the longer root, and the meg tooth is 155mm between the same points. Now I have a gleam in my e...

Fast forward to the summer of 2018, by which time I was working with Jessie Atterholt on paramedullary diverticula — laying the groundwork for what would become Atterholt & Wedel (2022) — and generally getting interested in all things neural canal related, including the weird expanded neural...
(na1) and single atlas intercentrum (ic1), and would probably have a pair of fused cervical ribs (r1). Everything else would be fused together to form the axis, including the atlas pleurocentrum (c1), which forms the odontoid process or dens epistrophei (etymologically the “tooth” of ...
