kidafro Posted June 1, 2017 Share Posted June 1, 2017 I recently acquired a shark tooth but I do not have a lot of expirience in this specific field and would like to ask what shark this comes from. I am certain it is from the Miocene period but I think it is a mako shark tooth.-Correct me if Im wrong. Pls*How much should I sell it for and how do I classify it Link to comment Share on other sites More sharing options...
ynot Posted June 1, 2017 Share Posted June 1, 2017 Poor picture with no scale. Hard to be sure what the tooth is. The Fossil Forum does not do appraisals. 1 Darwin said: " Man sprang from monkeys."

ynot Posted June 1, 2017 Share Posted June 1, 2017 It does resemble a "mako" lower tooth, but it is missing part of the root and is somewhat worn. They are common teeth.

Fossil-Hound Posted June 1, 2017 Share Posted June 1, 2017 Can't tell from here. Take a closeup without your hand. Could be a hemi. Do or do not. There is no try. - Yoda Link to comment Share on other sites More sharing options...

I can enlarge the picture without it blurring. I am 99.9% sure it is not Hemispristis. With most of the root missing I could only say it may be a mako, possibly I. desori. It could also be a sand tiger species. @kidafro do you know the location where it was found? This could help us more in determining what it could, but more importantly could not be. Saying it is from the Miocene is very world wide generic.

Like you said it could be a sand tiger but don't sand tiger teeth have the little barbs on both sides of the root? I always get confused when the teeth come from various locations in the mouth.

The cusplets (barbs as you called them) can wear or break off pretty easily. Also, there are multiple species of extinct sand tigers. I've seen them both with and without cusplets and even some with multiple cusplets on the same side. Here is an example. https://www.google.com/search?q=cusplet&rlz=1C1CHWA_enUS556US556&tbm=isch&imgil=DNlbg6067sMVoM%3A%3BSxUymdkGEHSx_M%3Bhttp%253A%252F%252Ffossilsofnj.com%252Fshark%252Fo_reticulata.htm&source=iu&pf=m&fir=DNlbg6067sMVoM%3A%2CSxUymdkGEHSx_M%2C_&usg=__HnSziYEf3TuNMGDXffD67IWlD6Y%3D&biw=1366&bih=662&ved=0ahUKEwjIsOGW95zUAhULxYMKHVfHBqYQyjcIQA&ei=li4wWcgNi4qPBNeOm7AK#imgrc=DNlbg6067sMVoM: Cheers, 2 Don't know much about history Don't know much biology Don't know much about science books.........

Yes sand tigers do have side cusps on there teeth. Some species on just some of their teeth others on all of them. Some sand tiger species have more than one side cusp on each side. Remember this tooth is very worn with a broken root. Often times sand tigers are found with the side cusps missing. 1 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...
