Fossil tiger sharks have been getting some more attention lately. Two pertinent papers were published this month. This morphometric analysis reduces Galeocerdo to six species: Galeocerdo aduncus, Galeocerdo capellini, Galeocerdo clarkensis, Galeocerdo cuvier, Galeocerdo eaglesomei , Galeocerdo mayumbensis. They agree with Physogaleus contortus being it's own species rather than a positional variant or sexual dimorphism of G. aduncus. They also contend G. cuvier back to at least 13.8 Ma. This report published today describes the partial skeleton of an immature dugong (

CMM finds Physogaleus aduncus possible associated dentition
WhodamanHD posted a topic in Fossil News
From the Calvert Marine Museum Fossil Club Facebook page, our shark people may enjoy this next twist in the debate: ”Associated shark teeth from the whale collected in 2008. During the excavation a number of teeth were uncovered around the ribs. All of these teeth are from a tiger shark. The upper and lower positions are a proposed possibility. However, those of you who follow the ever confusing world of shark tooth identification, you’ll notice the “upper” teeth are ones identified as Galeocerdo aduncus and the “lower” teeth are ones identified as Physogaleus contortus.

I purchased this tooth from Dakhla Bay, Morocco. It's 1.1 cm long and appears to be Galeocerdo. It was advertised as Galeocerdo alabamensis. However, I can't find records of that species from Morocco, or outside of the United States for that matter. I know that Galeocerdo eaglesomi exists in Morocco. This doesn't look like one to me. Anyone know what it might be? Thank you, Bellamy

I went out on a fossil hunt last Thursday to one of the streams I like to hunt at. It was only around 28 degrees F when I arrived so I didn't have the highest hopes. I ended up having my best day both quality and quantity wise! I found my first New Jersey hemi as well as my first tiger shark tooth. Also found a really nice sized sand tiger as well as one that would have been a monster if it was whole. Hope you guys enjoy!!

Went out to the Peace River yesterday. The water flow and depth were down to very workable levels. Weather was very nice after several days of below normal temps. I still needed the wetsuit due to the water temp, but it was a really great day to be on the river. After an easy paddle up river I found my targeted spot was at a level similar to where it was in October. I was able to easily pull the kayak up onto a sandy bank and step out with no effort. A check of the bank for about 25 yards in either direction failed to yield up any finds. With that I began working my way along the river

A little under the weather (and having truck trouble) but took a break for a few hours hoping to find more shrimp coprolites after recent thunderstorms. Humid, but not particularly hot, lots of frogs. Despite lots of digging in last week's spot, not much mixed in the gravel, mostly small broken stuff (one vert, one angel shark tooth, some drum teeth). I always wonder if I am 'mining' an area of the stream bed that was picked over 30 years ago. Finally found a mottled tiger shark tooth, relatively rare on that site. I have some small pieces drying but no strong suspicions of shrimp coproli

I was told this was a Tiger shark tooth found inland United States ans was a couple million years old. Now I'm not to keen on shark teeth but I don't think the information is correct. If anyone could shed some light on this it would be greatly appreciated thank you.

Hello. I purchased some tiger shark teeth and was hoping to get some ID help. The teeth come from various locations in Florida. The largest tooth is 1.25 inches (~3.2 cm). All the teeth have complex serrations. I believe the first row (#1-6) come from Galeocerdo mayumbensis. I am unsure about the second row and think they may be either Galeocerdo cuvier or Galeocerdo mayumbensis. Below are front and back pictures of the teeth. Thanks for any help.

Sorting my sharks' teeth. Not 100 percent sure about some of these. There are just enough differences to throw me. I used a flash because it seemed the best way to highlight the details. First picture front, second picture back. Thank you!

Hey all, This isn't so much a Fossil ID as it is a question. Can Tiger Shark teeth have smooth cutting edges if they're worn down enough? If so, then this tooth would certainly attest to that. I'm fairly certain that it came from the jaws of Physogaleus contortus (technically not a Tiger, but I call it one anyway). The strange thing is that it almost entirely lacks a defining feature of Tiger Shark teeth: serrations! The only evidence of a serrated edge are on the distal shoulder, but even there they are incredibly worn down. On the blade of the crown itself, the cutting edge is pe

Hey everyone! I know they technically aren't fossils, I have a drawer of modern shark teeth, of which many are starting to exhibit hairline cracks along the center of the teeth, which weren't there when I purchased them previously. Does anyone know why this is happening, and if so, how do I prevent this from happening further?
