PrehistoricWonders Posted October 31, 2020 Share Posted October 31, 2020 Hey, I purchased a large grouping of shark teeth a couple days ago, and it got here today. I was sorting them, and found a couple interesting ones, this was one of them. It’s very pathological, but I can’t ID it, I think it’s either a false tiger or cow shark, but I can’t tell. @Al Dente @digit @MarcoSr. TIA Link to comment Share on other sites More sharing options...
bthemoose Posted October 31, 2020 Share Posted October 31, 2020 I think that may be a cow shark upper tooth. The root looks like it to me, plus the angle of the serrations on the right side of the cusp in the second photo. Link to comment Share on other sites More sharing options...
digit Posted October 31, 2020 Share Posted October 31, 2020 Agreed. The beveled root that tapers to a thin edge at the base suggests a cow shark to me as well. I haven't seen a lot of these teeth in person but it does match the look of the ones I've seen. Cool tooth. Cheers. -Ken Link to comment Share on other sites More sharing options...
PrehistoricWonders Posted October 31, 2020 Author Share Posted October 31, 2020 Wow... I’ve never seen a patho cow, definitely not what I we expecting to get! I was leaning towards cow, but wasn’t sure. Thank you! Link to comment Share on other sites More sharing options...

Coco Posted November 1, 2020 Share Posted November 1, 2020 Hi, I suppose cow shark is Hexanchidae.

Coco Hi Coco, Yes, "cow shark" is a common name for genera in the Hexanchidae. I think it's because these sharks, or at least a couple of them, have blunt noses. Some species have more than one common name in English depending on the area they are occasionally caught. Jess Link to comment Share on other sites More sharing options...

Marco Sr. Hi Marco Sr., Does it look to you to be pathological or just worn/weathered? Jess Link to comment Share on other sites More sharing options...
Coco Posted November 2, 2020 Share Posted November 2, 2020 Hi, Thanks Jess, that’s what I thought, but with vernacular names I’m never sure because, as you say, there are several names and it’s the same thing with us. It doesn't seem pathological to me, it is for me the third superior tooth after the symphyseal one because we see the remains of denticles on each side, but it is very worn out.

Jess Common names of sharks can vary greatly in different parts of the world and sharks can even have multiple common names in the same country. It is always best to use scientific names like "Hexanchidae" for a family instead of "cow shark" to avoid any confusion. Marco Sr. "Any day that you can fossil hunt is a great day."

PrehistoricWonders Posted November 2, 2020 Author Share Posted November 2, 2020 I’m not positive that it’s pathological, but looking at the sides of the tooth it looks to thick and seems to have an unnatural curve to it. Link to comment Share on other sites More sharing options...
