Weekend Florida Fossil Finds

[Age_old]

I spent the weekend scuba diving in the Peace River, Florida for fossils. I only used two tanks for about 5 1/2 hours of bottom time. I found a perfect 3-inch meg, whale vertebra fragments, a whale ear bone, tortoise leg spur, horse teeth, gator teeth, glyptodont scute, fulgurite, and a bison ankle bone. Overall, it was a nice haul and a great time.

Hey Sam, Those are absolutly Aweome Finds! Those two large sharks teeth are in exquisite shape considering that they still have the fine detail. Is that smaller one a large Tiger shark tooth? (fourth photo)

Dennis, that is a nice upper Hemipristis serra tooth. Compare a tiger shark tooth with a Hemipristis tooth here:

Thank you, Dennis! Just like Harry said, smaller shark tooth in the fourth picture is called a "snaggletooth" or Hemipristis serra shark tooth. They were similar to tiger sharks, but the snaggletooth was bigger.

I trust you're talking about the size of the teeth of these two, very different species. Tiger sharks are the much-larger sharks. Furthermore, the average size of all tiger shark teeth (say by weight, 'cause they have different forms) is almost certainly greater than the average of all Hemipristis teeth.

I say this based on dealing with thousands of these teeth over many years. I do realize that some large sharks can have tiny teeth (whale shark is an example); but, that is not the case for tiger sharks.

I agree completely. I just meant the hemipristis teeth generally have a larger maximum size than the tiger sharks. I was trying to compare teeth, not the actual animal. I appreciate the clarification.

Okay guys! I still say they are awesome finds!
