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!!

Jaekelotodus trigonalis ? from Kazakhstan, Mangyshlak,
Brett Breakin' Rocks posted a topic in Fossil ID
Hi There, I just wanted to confirm that I think (?) these are examples of the large Sand Tiger shark from the Chattian. Jaekelotodus trigonalis ? ... This time period is not one I'm yet familiar with. Though, it is in a similar area to where the O. auriculatus I just received was found. Mangystau (Mangyshlak), Kazakhstan The preservation in this area is poor but the teeth are much larger. You can see the cusps have been worn down/away @Al Dente Cheers, Brett- 8 replies

Slipped out to the wooded creek. Children(?) have been busy hunting, they dig big holes near the creek bed? Maybe they know what they are doing. I was hoping some spots would yield cow shark teeth, but the kids have been busy in those areas. Guess being out of school so long has them bored, or more likely their mothers want them out of the house. No one was out today. Most areas I hunted were full of gravel and I found lots of broken stuff (not shown), nothing of size. I found a few tiny teeth which might be sand tiger symphyseal teeth; the roots look right , but they are smaller than usual? A few imperfect angel, one tiger (rare for this spot), and the majority sand tiger spikes. A few Tilly bones, vertebrae and some elongated curved teeth or bones. I see the poison ivy coming out everywhere! Spring peepers are abundant.

Hello. Does anyone know the species of this sand tiger shark tooth? It is from Florida and is 0.8 inches (2 cm) long. Thanks.

I’m trying to ID the tooth at the center of this spectrum. To its’ left, Sand Tigers. To its’ right, makos. But the specimen in the middle is... a bit of both?

Micro Fossil Report- Our first foray into the world of micros
fossilsonwheels posted a topic in General Fossil Discussion
I thought it would be fun and possibly helpful to other collectors to discuss the results of my first foray into the world of micro fossil exploration. I had purchased some quantities of micro matrix from two different formations and they provided vastly different experiences for me as a collector. I got a vial of micro fossils from the Neva formation which is from Kansas and is Permian. This stuff really proved to be quite a challenge and was not ideal to start with. These are TINY fossils and I was not equipped to handle such small fossils. Identifying the shark material was challenging but not nearly as challenging as just handling them. My first attempt to put a fossils on a slide resulted in me crushing a tiny partial Cladodont tooth. I was not happy with myself but it was a very teachable and humbling moment as I did at work in front of young co-worker who has developed into quite the shark fanatic. Once I figured out what NOT to do with the small fossils, I did find a groove and was able to find some interesting material for our display. I found a few shark denticles ( I think they are anyway lol), a possible spine, and a few partial teeth including one that looks similar to an unpublished species of Cladodont shark called Maiseyodus. There was not a lot of shark material and it was hard to work with but I plan on picking up another vial. I will not go through until I have better equipment though but I would like to continue the explore it. The goal was too add some Permian shark material from a marine environment to contrast the freshwater Permian stuff we had. In that sense, we accomplished our goal and I did really learn quite a lot so it was a positive result but one with plenty of bumps in the road lol The other micros were from the Cretacoeus Mesaverde formation and was Colorado. This was much easier to work with as far as size goes but there was much more actual matrix to deal with. I was also more familiar with the fauna and I had a much better idea of what to be on the look out for. It did not take long to find a few shark teeth. I opened the vial, dumped it on the tray and right away saw some partial teeth I could recognize. A few Hybodont partials were apparent very quickly as were some partial Sand Tiger teeth. There was also an interesting partial that I have not posted yet but might be a Cretalamna. I also found a few fossils that I think are ray dermal denticles. The really interesting stuff was found when I started searching the bits of matrix and the smaller fossils. Three little fossils absolutely made this a grand slam for me. I found what looks to be a Chiloscyllium tooth. It is fantastic shape and sits on top of a little piece of matrix really nicely. My ID looks to be okay as I did post here on the forum. I was really thrilled to find such a nice tooth. Another was posted on the forum and though I have some work to do to cement the ID, it MAY be a Cat Shark tooth which is one I have been searching for. Separating it from the matrix makes me nervous but I am practicing before I do it. I am really hoping it does turn out to be what I think it is but either way it was a fascinating find and thanks to some awesome TFF members led to a far better understanding of cat shark fossils. The third has not been posted yet as I need to take a closer look at it but when I first saw it, I thought it was a Rhinobatos which was another one I had been actively looking for. I got excited, put in a gem jar and put it in the display but I will take a better look this week. There were some interesting non-shark fossils too that I will go through at some point and quite a bit of poo as well lol I consider this to have been a complete success. We added some new sharks to the display and succeeded in furthering the diversity of sharks we can talk about. I need to get some equipment for exploring micro fossils at home and I need to work on the handling of the fossils. I need to learn how to separate small fossils from bits of matrix and I can always stand to sharpen my ID skills but this is a pretty important development for us. With some recent family events and two college aged kids depending on me the fossil acquisitions will slow down considerably. I can not buy a lot going forward so this is a fantastic and inexpensive way to continue to explore fossils, particularly Mesozoic sharks. A little bit of money spent on some matrix will yield fossils we can use. I do not live in an area where there is much fossil hunting to be done so this is also a way to self collect some material which is really satisfying. It has also been a great thing to have during my fathers illness and death as it kept me busy and my mind sharp. I can see a new addiction forming and it is a good one to have. In addition to adding some more from both of the above formations, I am going to pick up some Atco stuff and Kamp Ranch matrix too in the near future. That will keep me busy and I am sure we can add some more interesting fossils. This micro newbie is going to work on becoming a micro not-so-newbie lol I will post some pictures in the comment section.- 9 replies

Needed to get out and get some exercise. Relatively cool and dark in the morning, the full foliage shade was nice, surprisingly little water in the creek. I worked one spot hard, found a few partial ecphora, lots of sand tiger teeth, a few angel and drum teeth. A bonito nose a Tilly bone and what probably was once a bonito nose. One three pointed cowshark tooth which I lost when I fell. The highlight was a nice hemipristis (don't find many of those or tiger or mako in this site. And no megs). Bits and pieces drying to go through later.

Hi all, I recently went on a trip to Brownie's Beach in Maryland in search of Hemies, and I came home with some pretty good little teeth and a few decent sized ones. However, there was one tooth that I found I could not identify. I am not really sure what shark it belongs to, it sort of resembles a sand tiger but the root is very robust and thick. Im more or less lost as to what it could be. Wishful thinking, but I thought it might be a baby megatooth shark or a mako or something along the lines of that. Its a long shot, but I thouht i would ask to see if anyone else could Identify it, haha!

Hi so I have been hunting my favorite spot recently, and ever since I first came to this spot I have noticed a good amount of sand tiger teeth popping up, but only in this 10 foot radius. Is it possible that all of these teeth are from the same shark. They all range in similar size and I have only ever found them in this one spot. for every nice one i have pictured. I found 10 more broken ones just missing the roots.

Made two back-to-back trips to the beach, the first trip had too much surf, the second too high a tide. We had a wind storm from the north and I expected stuff on the beach (but a quick glance at the tide lines left on the beach revealed nothing but shells.) First day didn't find much, surf was strong and I lost three in the crashing waves. It was warm out, and i tired of chasing the little teeth. Today was better results-wise. Much cooler and a manageable dropping tide. Walked up and down the beach picking up the occasional tooth (always amazes me that you can find teeth every pass, must be uncovered in the wash, which wasn't moving them today). Good day for makos-- three, one inch long and one or two smaller ones. The shell line in the wash was much thinner than usual, maybe made the teeth easier to see? The shrimp coprolites were deeper in the water than the teeth.

1. Hemipristis serra: One of my first teeth of the day, found in the water. Small, but nice colors and perfect serrations. 2. Carcharias cuspidata: Flawless sand tiger. Symmetrical and super sharp, with both double cusplets intact. 3. Galeocerdo aduncus: Gorgeous tiger, almost looks like a G. cuvier because of size. Very nice root to crown contrast. 4. Odontocete tooth: Little porpoise/dolphin tooth with a long, thick root. In very good condition. 5. Ecphora sp.: A very nice small Ecphora, nearly complete, just missing the white part at the top. Rare to find more than a fragment of these at Brownies. Cast your votes! The poll will end in three days, on April 4th at 3:00 p. m. EST. Hoppe hunting!

Hi there folks, I recently received this lot as gift, but it came with no ID. Is it possible to get an ID from this pic? They are all from Morroco. Thanks in advance.

Tried to get out before the ice storm in search of cowshark teeth (found none and hunted hard). Lots of small sand tiger teeth, including a crooked one and a symphyseal, and lots of split teeth. Lots of drum teeth, (the dull side is more interesting than the glossy side). Four angel teeth that stand up on their triangular base, two whose root is damaged. Two or three mako (broken). Lots of small triangular teeth (dusky, bull, gray? not sure what all they are). Lots of batoid/ skate teeth, but no stingers or denticles. One whole vert and a small disc echinoid. Lots ofsmall 'whale bone' and bits to go through. Not what I was after, but quantity if not quality was good.

(I will now be using the poll format, so you can actually click your favorite and the poll will keep track of the votes) 1. Carcharocles chubutensis: MY FIRST MEGATOOTH! A bit of damage near the root and a missing bourlette, but a gorgeous tooth nonetheless. The serrations are absolutely killer. It’s about 1 ¾ inches. Colors completely changed when it dried. I. Am. Ecstatic. 2. Carcharias cuspidata: Very large sand tiger with a beautiful hooked double cusp on one shoulder. Excellent preservation, and certainly a necklace quality tooth. 3. Notorynchus primigenius: A perfect little cow shark tooth. Found in the cove within my first five minutes of collecting. Not very big, but in fantastic condition. 4. Isurus desori: Incredible little mako. It is absolutely pristine, and still sharp enough to cut you. Has that beautiful Brownies blue coloration on the enamel. 5. Carcharocles sp.: Oh, what could have been...this is the tip to what was probably a huge Megalodon tooth. Based on the thickness of the tooth, it would have been much larger than the meg that I found. Still a great find! The tip of a monster.
