simply as 'protuberances'. There is a 1997 paper by
Czerkas that discusses Carnotaurus skin, but I haven't got a copy. In a titanosaur paper, Lindoso et al. imply they could be osteoderms, but don't specifically say. Does anyone have a copy of Czerkas 1997? If there is uncertainty in the literature over these bumps, what should wiki refer to them as?
1206:
I just checked
Czerkas 1997 again, and he refers to these bumps as "conical studs", stating that they are "probably made of a hypertrophied cluster of compacted scales, similar to what is seen in the dermal spines along the dorsal midline of hadrosaurs" and "There is no indication of a horny core".
909:
Looks great to me, now the article should be fully up to date! Perhaps the restoration could now be moved from the discovery section (where it is not so relevant) to the skull section, which now has more space? And if we're lucky down the line, a map could then be moved to discovery, or maybe I can
987:
We could maybe move the "skull cast" photo of the skull section down to "Brain and senses" (which has some space), to have space for the restoration? This would leave space in the description section – you suggested to add a map. Do you know any file that can easily be modified to make such a map?
793:
But I see we also have conflicting information: Bonaparte (1990) states that "Both lower jaws are completely preserved with all their teeth. Unfortunately some teeth were fragmented when the jaws were being separated from the skull." His skull diagram shows only few missing parts in the teeth, and
1136:
I don't see sandwitching on my screen, but I made one diagram smaller where images are most crowded. There is no citation needed; that single sentence without a citation is just editorial, a summary of what follows in the three paragraphs to come; it is just providing structure to the article and
969:
The main thing is that I think it would be good to have the restoration now in discovery somewhere in the description section, but there isn't much room. Another thing that could maybe be cool is to make a double image with the current tail muscle cross section and this 3D reconstruction from the
822:
I do note that 1) the skull diagram of
Bonaparte, in the upper jaw, shows more complete teeth then the actual skull with plaster and all (photograph in the same paper); 2) that the missing parts indicated for the lower jaw in that diagram simply are the missing parts in the reconstruction (so all
778:
The source doesn't state that the teeth as reconstructed are wrong, but it does say they are fantasy. There is no reason to assume that they are any different to those of all other abelisaurs, and the replacement teeth have short crowns as expected. Yes maybe we should discuss this at WP:Dinoart.
1190:
actually are, but osteoderms by their name are bone in the skin, whereas 'feature scales' is a term usually used by hadrosaur workers (i.e. Bell 2014) to describe extra large standalone scales or the midline structures, 'midline feature scales'. Reading
Bonaparte et al. 1990 describes the bumps
823:
plaster is shown as preserved, which is misleading); and that 3) the 2020 skull paper has an updated diagram that shows much shorter tooth crowns. I tend to think that the 2020 paper is correct. But yes, let's just wait for another published opinion on this. --

As part of the FAR process, I ticked this as "satisfactory", but wanted to note some recent sources that should probably be incorporated into the article, as follows.

Done. In fact, the article was already saying these structures were scale aggregates, and was therefore contradicting itself. Not sure how I could not see this. --

So should we assume that our restorations here, and of most other abelisaurs, are wrong? Here's a restoration based on the new paper, looks pretty smooth:

Wow, that was unexpected! Doesn't that also mean our photos of mounted skeletons are wrong? Or maybe it isn't too visible there?
