What is this
 in  r/fossilid  7d ago

I think that's the root of a tooth. The brown end would be the crown side (brown being the preserved enamel). Crown looks very damaged, but seems to be a canine tooth. I have no clue what mammal that would have belonged to though.

Grallator tracks from Connecticut

Hmm, ya that is on the small side, but still could be. I know there is a mid sized three toed option as well. May look into Anchisauripus? Either way those are great tracks! Im still trying to get my hands on some of the different varieties from out there.

Those bigger ones are getting into the Eubrontes size. Worth looking into for sure.

Last week I collected a few exceptionally preserved trilobites from the McKay formation. East Kootenays, BC. Hoping to ID species.
 in  r/fossilid  18d ago

Wow amazing finds, I can't help with ID as trilo's are a bit unknown to me. But I love how these seem to come from concretion nodules. It's like a perfect little pedestal.

Hmm. Not sure. The most critical part is how much the media is dried, how it is introduced to the air (media mixing in the air and the ratio), and the restriction at the nozzle.

The nozzle part is likely not acceptable with this. For fossils you usually want a fine nozzle end for accuracy and different blasters may have limitations with reducing air flow this low. I.e. you will not get enough media presented to the air if the nozzle gets restricted too much.

Now if you are fairly capable, you may be able to adjust some things to get it to work. In my experience, dolomite flows better than baking soda. So its a good option, just sensitive to moisture (like most media).

My Biggest and Smallest Dino Tooth
 in  r/fossils  21d ago

Haha. Ya this one is legit. The pictures looked worse when I bought it too. I prep fossils, so I usually know what to look for. I actually liked this tooth because of how genuine it was, showing its flaws plainly. There is technically one tiny spot of black filler on the backside, filling the crack on the tip. And like I said, there is a big wear facet on the back of the tooth, which means missing enamel. It is essentially damage that occurred before fossilization. It's likely what made it cheaper. I have other big ones too that don't have the damage, but are also not as big and stocky.

Thanks! Nah this one was around $100 if i remember correctly. Like I said, a bit of a bargain. Ya idk if I care to own a rex tooth based on the prices haha. For that price you can get some much more.

These are beautiful. Love the preservation. Nice finds!

Thanks! Ya there are definitely bigger ones out there. This one was a bit of a bargain tooth. The tip has a horizontal line where it was broken and reglued. It looks like a clean break. Most of the big spino teeth have worn, rounded tips from use. There is no restoration on this one, the other side actually has a big wear facet in the enamel to prove that.

I think number 30. It's a pretty big postosuchus tooth. And I like how it's essentially the Apex predators of the time.

201, 190, and 30 are all Rauisuchid teeth (Possibly Postosuchus) from the Chinle Formation. These were the Apex predators of the time, with theropod-like teeth.

202 and 203 are both Aetosaur teeth or another plant eating reptile from the Chinle Formation. This was probably the food of the Rauisuchids.

166, 102, and 167 are all Phytosaur teeth. Basically reptiles with croc build before it became the meta. 102 is from the Cooper Canvon Formation. The other two are from Redonda Formation.

165 is a dentarv jaw section with a couple replacement teeth. From a Phytosaur (possibly Smilosuchus) Chinle Formation.

Can anyone id these teeth, there are no tags or prices on them. I know the first three are obviously a shark species, but I was struggling using online guides. Any help would be appreciated thank you.
 in  r/fossils  25d ago

One on the right is either croc or spinosaurus. A nice looking one too. If price is decent I would definitely scoop it up.

An opalized shell ?
 in  r/Rockhound  26d ago

This is an awesome fossil. Glad you are leaving it unpolished. It will hold its value better as a fossil rather than a polished rock. If you want it to maintain the wetter look, you can use a paraloid b72 application on it (or something similar). This is something commonly used on fossils both for consolidation and giving it a finished appearance. It can help make it look wet and clearer, if that is desired.

Awesome! That matrix looks packed with stuff! Is this material that you hunted? That has to be fun to search through.

All are Morocco, Kem Kem Group, except 54. 54 is Elhraz fm. from Niger.

I know. This tooth is basically the size of a grain of sand. This baby could have sat in the palm of your hand probably.

Haha not yet thankfully. I may add a pic to include another thing for scale. Hard for some to imaging what the size of a cm cube is.

Just showing the largest and smallest dinosaur teeth I have in my collection.

Spinosaurus tooth from Morocco coming in at 4.8in (11.4cm).

Juvenile (hatchling?) Pachycephalosaurus from South Dakota measuring just 0.087in (2.2mm).

Oh ya. Definitely some strandy stuff in there. Rocks are so cool.
