Rapp Creek and Beach hunting


Recommended Posts

Out of action for a bit, but figured a good time to post what I have been collecting since coming back from Singapore summer of 2018.  Starting with sandtiger shark teeth, since they are the most common here.  Really like the little hook cusps which I seldom see on both sides on the biggest teeth.  Cusps are most prominent (but often nubs) on the lateral(?) medium sized wider, root teeth.  Symphyseal teeth are not that rare (wish they were cowshark!); often I think one is a split tooth until I examine it carefully; the roots are distinctive.  The small teeth may include a few that are not sandtiger, but I'm thinking since they are most common, many of the non-descript small teeth probably are sandtiger.   Scale shown for all the teeth in first photo is in cm.

Thanks Tim!  Common teeth, but it's what I've got.  Having hip problems so hope to post some of my other "groupings" before I can get out again.

Angel shark teeth are probably the second most common; some are very small and I also tend to lose these in screening or in the shell bits or sand and gravel that end up in my bucket. Although squatina teeth are difficult to differentiate across species, mine seem to be Miocene.  I have not found any on the beach five miles away where I mostly hunt.  The teeth are different from anything else, a base (root) that is an elongated triangle.  The small blade is curved and attaches to the side of the root, not the center.  Some angel shark teeth seem impossible to stand up on their roots, others seem impossible to flip over.  I tried to take photos of the bottom of the base (roots) as well as the flipped over teeth.  there were also some where the base was broken or I just gave up on standing or flipping (may have some other small teeth mixed in; they are on the opposite side of the scale tape).  Scale is in cm.
