Jul 20, 2014 · Shark vertebrae tend to be preserved as just the centrum (the hockey puck-like disk) with two openings on top and two on the bottom where the hemal and neural arches were attached. The arches were cartilaginous in life and disintegrate quickly after death.

Apr 12, 2011 · A somewhat typical Cretaceous fossil shark fauna including Paranomotodon, Cretalamna, Squalicorax, Scapanorhyncus, Cretoxyrhina(?), Ptychodus, etc. are found in these sites. Many (all?) of the teeth found in the MN granite quarries is also found just across the MN . state border in SD where the granite is also mined.

There were many small shark teeth to keep me picking fossils out of each sieve, mostly were this lighter color, not normal for the Peace River..

Apr 2, 2018 · Shark Tooth Island is located in Wilmington, NC, just off the shore from River Road Park. If you're standing at the boat ramp facing the river, the island directly in front of you is Keg Island. At low tide, the upriver side of the island can have some specimens to collect, but I never had as good of luck on Keg Island as I did on Shark Tooth ...

Aug 14, 2018 · With that question, we have a line of inquiry: what, and how, were they eating that might let this make sense? We should maybe not use modern sharks in modern oceans to compare to a 350 million year old environment. Let's begin by placing "shark" in air-quotes when referring to Edestus. They are as unrelated to Charcharius as we are to Dimetrodon.

May 1, 2019 · I just looked at a post that I did almost 1 year ago about Hogtown Creek in Gainesville and this post is almost exactly the same. It was a quick visit to Alfred Ring Park, about 45 minutes, and again I only found some miscellaneous bone pieces, Ray and shark teeth. The temp was hot, 86 degrees, and the water was cool- it made for a great time.

Nov 28, 2020 · The ammonites you found are Prionocyclus macombi and the shark teeth are from Ptychodus whippeli. The little "bottle cap" oysters are Lopha lugubris while the other bivalve is Inoceramus...they look to me like I. dimidius though there are two inoceramid biozones in that formation. The mineral is calcite...very common in concretions.

Sep 25, 2019 · I love the shark teeth but I really was hoping to find a mosasaur tooth or vertebra...but I was happy to find a fish vertebra! My first one! And this MAY be a very pyratized ammonite...I think. I hope. The HIll Country Fossil Club! Our Hunting Grounds...there is a REALLY large pit behind those piles
