Dinosaur dental histology

 * ... that dinosaur teeth have rings like trees? Source: "You are strongly encouraged to quote the source text supporting each hook" (and [link] the source, or cite it briefly without using citation templates)
 * ALT1:... that you can count lines in dinosaur teeth to determine their age? Source: "You are strongly encouraged to quote the source text supporting each hook" (and [link] the source, or cite it briefly without using citation templates)

 * Symbol possible vote.svg Article is new enough and long enough, but not well referenced. Most of the Preparation section and its subsections are unsourced. QPQ is done, and no copyvio found, but the referencing issue needs to be fixed. -Zanhe (talk) 23:53, 1 December 2017 (UTC)
 * I have contacted Dinohk about this. Graeme Bartlett (talk) 03:15, 4 December 2017 (UTC)
 * Symbol redirect vote 4.svg Referencing is now fixed by Dinohk. Graeme Bartlett (talk) 01:47, 5 December 2017 (UTC)
 * Could you please list some quotes in the sources which support the hooks? The sources are very technical and without a background in palaeontology, I have difficulty understanding them. -Zanhe (talk) 03:09, 5 December 2017 (UTC)
 * Dinohk put this in the article: Greg Erickson noted "Dinosaur dentine exhibits growth lines that are tens of micrometers in width. These laminations are homologous to incremental lines of von Ebner found in extant mammal and crocodilian teeth (i.e., those of amniotes). The lines likely reflect daily dentine formation, and they were used to infer tooth development and replacement rates." from Incremental lines of von Ebner in dinosaurs and the assessment of tooth replacement rates using growth line counts .

 * That source only mentions growth lines, not rings. Is that another source that mentions growth rings like tress? Or you could change the "rings" in ALT1 to "lines". -Zanhe (talk) 05:50, 10 December 2017 (UTC)
 * The growth lines will appear as rings or lines depending on the orientation of the thin section. I do not have any images clearly showing the rings that can be uploaded to the page so I will just change the wording to lines to avoid confusion. — Preceding unsigned comment added by Dinohk (talk • contribs)
 * Symbol confirmed.svg I went ahead and changed "rings" to "lines" in ALT1, which is now fully supported by sources. ALT1 good to go. -Zanhe (talk) 19:51, 10 December 2017 (UTC)
