  1. I've not had a chance to post my finds here in a while but over the past few months I've found some new specimens of Lower Carboniferous/Mississippian marine shark teeth I wanted to share! These were collected at various sites in the Midland Valley of Scotland from the Blackhall Limestone, an extensive formation with interesting variations in fauna at each different locality. Ctenoptychius sp. Anterior tooth in lingual view, 6mmx7mm.
  2. Sharks of SC

    Today's Massive Desori Mako!

    Hello Everyone! It's been a minute since I've had the pleasure of finding any fossils worth posting here, but I was lucky enough today to squeeze in a couple hours of hunting. I noticed several sets of footprints around my usual hunting site - others had picked through the material recently. Undeterred, I made my way along the river visually scouring every square inch of exposed grey-brown Oligocene formation and gravel. Im glad I stuck with it because I was rewarded with several nice (albeit small) teeth from the extinct mega-tooth white shark, Carcharocles angustidens as well as a slew of smaller teeth. Then, just as I was ready to start hiking back to the car, I noticed the root of a VERY large mako tooth sticking out of the ground. When I pulled it up I was reminded of the sword in the stone..it just kept going and going. At a little over 2.8" it's one of the largest Isurus desori teeth I've ever personally seen. It's in great condition with exceptional color to boot. Thanks for taking a look and as always... Happy hunting! SOSC

    'Heterodontus' upnikensis

    A - lateral; B, C, D - anteriors. Anterior teeth have typical of Heterodontus V-shaped root and marked cutting edge. Unlike H. canaliculatus anteriors, anteriors of ‘H.’ upnikensis have more convex labial side (so that cutting edge is situated in the middle of the lateral surface) and no lateral cusplets. Crown generally widens near the base, so most teeth have regular triangle shape of a labial face. Teeth located closer to symphysis display more mesiodistally compressed crowns. Enamel is smooth on both faces. Lateral teeth are also different from H. canaliculatus: they have lower and shorter central occlusal ridge and lateral ridges are highly anostomosed on both sides, so that complete tooth ornamentation has a net-like appearance. ‘Heterodontus’ upnikensis is an enigmatic species. No associated tooth set has been found yet, consequently it is impossible to tell that a given set of laterals actually belong to ‘H.’ upnikensis. There is a possibility that lateral teeth described here as ‘H.’ upnikensis here belong to another Heterodontus species not represented by anteriors in Kanev collection. They were assigned to this species because there is generally some degree of tooth plan similarity between anteriors and laterals of the same species. Laterals described here have: 1) relatively weak and short central occlusal ridge; this trait is similar to ‘H.’ upnikensis shorter cutting edge because of lateral cusplet absence; 2) more bilateraly symmetrical crown shape and ornamentation across the central occlusal ridge than in H. canaliculatus; this feature is analogous to relatively equal thickness of labial and lingual face on ‘H.’ upnikensis anterior teeth. Also, anteriors of ‘H.’ upnikensis are a lot more common in studied locations than H. canaliculatus, and the same trend applies to two found Heterodontus lateral teeth morphotypes with H. canaliculatus teeth being a lot scarcer.
