Still_human Posted August 29, 2019 Share Posted August 29, 2019 Does anyone have, or can find, a picture of a fossil of the head horns of hybodus? Not the fin spines, but their "devil horns". I can't find any pictures of them that include visible horns...or at least that I can make out. Link to comment Share on other sites More sharing options...
fossilsonwheels Posted August 29, 2019 Share Posted August 29, 2019 These should help you a little I think. This will give you the basic idea of what the cephalic hook (spines) look like in Hybodonts. You may be able to find a few more, search Hybodont cephalic spine, hook, or clasper. I have seen them referred to as all three. There is also a really nice one currently on online from England that gives you a great idea of what they look like. I believe the njfossils.net site might help you too. 2 Link to comment Share on other sites More sharing options...
grandpa Posted August 29, 2019 Share Posted August 29, 2019 Try this for artist rendition and placement of horn. https://walkingwithdinos.fandom.com/wiki/Hybodus?file=Head_on_hybodus.jpg Link to comment Share on other sites More sharing options...

I'm surprised anyone uses that as a term for them, especially in the scientific community, cause sharks already have "claspers", and I think that's the only true scientific term for THOSE...other than genitalia...and the many other general, and slang terms, I guess.

Randyw Posted August 30, 2019 Share Posted August 30, 2019 Ummmmmm yes the claspers are only on males... 1 Link to comment Share on other sites More sharing options...
Miocene_Mason Posted August 30, 2019 Share Posted August 30, 2019 You should see Falcatus falcatus, very strange cephalic claspers. 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

Male Chimeras have cephalic claspers so that is a true scientific term however that website is the only place I have seen that term used for Hybodontids. I only put it out there as an additional term to use if you search for images. I do not know if only male Hybodontidae had them so I can not comment on how accurate that is. 1 Link to comment Share on other sites More sharing options...

I didn't know they were sexual in nature, or called claspers, though. I'm still surprised they call horns and such "claspers" however, since the claspers are also the actual male genitalia. So a male of some shark species have 2 seperate things called claspers...strange. Link to comment Share on other sites More sharing options...

THAT makes much more sense to me. It makes perfect sense to me that they're also clasper spurs do to function, it still just comes off as strange to me calling something on a sharks head a clasper anything.

Nice! These spines are very fragile so they are difficult to find in good condition. I have a couple of isolated, smaller ones from the Hell Creek Formation (Maastrichtian), Buffalo area, South Dakota. One is missing most of the spine but has the base; the other has the spine but is missing some of the base. 2 Link to comment Share on other sites More sharing options...
