I'm busy at the moment working on an off-wiki project that led me to this page and this page. The latter is a site at a sort of Fossil Wiki...it's several tens of times longer and much more informative. I don't like how it's written, but it proves that this stub needs expansion. If someone has time, would they mind taking a look at an expansion on this stub? Bob the Wikipedian ( talk • contribs) 02:31, 8 July 2009 (UTC)
I just came across an illustration of Helicoprion from 1906. I'm not sure whether it would be useful to the article, but it's probably in public domain, or at least its copyright has expired. It appears to depict the animal as something other than a shark. Here it is: [2] Gary ( talk) 21:59, 19 March 2010 (UTC)
The body of the page says this species existed from 280 mya to 225 mya, but the box on the right lists it from 310 mya to 199.6 mya. BlackMetalWhiteGuy ( talk) 08:40, 3 July 2011 (UTC)

I've heard rumors that scientists have found Helicoprion fossils with bits of fossilized cartilage. Can anyone link to any photos? Kurzon ( talk) 12:33, 13 March 2013 (UTC)
This is just a quick question. Are the question marks next to the species name meaning that they are dubious species.-- VaderRaptor 11:13, 25 October 2020 (UTC)
