Let Me See Your Recent Selachian Jaws !


Coco

Recommended Posts

Most of members of this forum are interested in fossil sharks. But it is sometimes useful to compare these fossils with the recent jaws for understanding the various teeth of every species and their positions in the jaw (see this thread)

I propose to put here your recent jaws of selachians, to obtain a good range of existing species actually.

I begin with the largest shark family, the Carcharhinidae. They are difficult to identify because these species are very numerous and a lot of them have same lower teeth...

As I shall make my photos, I shall integrate the new ones into this initial subject in the order of families.

CARCHARHINIDAE

Carcharhinus acronotus - Blacknose shark

Coco,

Thanks for the photos. It is good to have modern reference specimens and photos of whatever you don't have. Some people will buy jaws just so they take the teeth out and glue them in order by quadrant on sheets especially when the jaws are damaged but the species is unusual. Having these references allows collectors to see for themselves the often subtle differences and variations from jaw position to jaw position. Your examples of Carcharhinus species are particularly helpful to collectors because each of them has a fossil record. Jaws of modern species without a known fossil record (as in the case of some deepwater forms) expose blank spots in our knowledge and show us what to keep an eye open for when collecting in sediments representing the same types of habitats of the descendants or relatives.

Most of members of this forum are interested in fossil sharks. But it is sometimes useful to compare these fossils with the recent jaws for understanding the various teeth of every species and their positions in the jaw (see this thread http://www.thefossilforum.com/index.php/topic/10818-heterorodontie-of-selachians/page__p__123920__fromsearch__1#entry123920 )

I propose to put here your recent jaws of selachians, to obtain a good range of existing species actualy.

Hi,

Trilobite Guy, They are mine. I bought most of them for a very long time, on Eb-y. Someone are maybe badly identified because the salesmen did not know necessarily what they had, and when I verified their names, I had not all the tools which we have at our disposal today. I didn't verify the names for a long time.

Thanks a lot Paleoc for your comment. You are right ! I corrected my posts...

i love the jaw because its really cool to see just the jaws, because then you can see the huge differences between each species :wub: .........are the jaws pricy$$?

RickNC : do you have any pics of mako ?

Trilobite Guy : I am interested in recent selachian jaws to observe the multitude of sorts of teeth and their positions in a jaw.

My more expensive jaw is a big Galeocerdo cuvieri (112,50 € = 149,21 US$) I have bought for a friend, but I done a mistake with the price. I thus kept it for me. My less expensive jaws are the ones I prep myself (most of them are rays).

FossilForKids : your Hemipristis elongatus is nice. Do you have lower fossil teeth of Hemipristis ? (serra ?).

Alopias : thanks. It is just the beginning ;)

Skulls Unlimited has some available. I thought about buying one. I have a small set of tiger shark jaws I got somewhere years ago.

I had a look on Skulls Illimited, it is written "We no longer accept shark jaws for cleaning"... Really, it is a special work to prep some selachian jaws.

Here is the selection at SU. Most of theirs are replicas. The natural bone mako's are at the bottom of the page. I can get a pic of my small tiger here sometime soon:

After looking at your photos, I think I am able to ID my mystery jaws as a silky shark! Shape is right, and count is right, not to mention those weird itty bitty center teeth! Thanks for the post!
