Dinosaur tooth (I believe the guy said it was from a Tyrannosaurus?!) and then the tooth under the microscope so you can see the serrated edge and the wear and tear.

The collections facility had their open house today which is always super cool! I get so distracted so I often forget to take photos oops.

Suspected agatized tooth with crystallization inside from Bob Creek Wayside, Lane County, Oregon. April 3rd, 2017. 

I mean, this has to be a tooth, right? Maybe a wee mollusk of some sort, but it’s certainly something fossilized and it sure LOOKS like a tooth. IDK.

My parents bought me a baby megladon tooth! I love it!

New collection of some recent creek finds!

Found a nice old coyote or dog tooth, a leg from an old porcelain doll, a really nice crinoid stem, a fossilized bivalve shell broken in half with innards that look like a weird pearl, old glass fuse, some really pretty bits of colorful pottery and glass, massive chunks of bonfire glass and melted aluminum, a nice little geode with some chunky little quartz crystals inside, and tons of other rad crinoid, brachiopod, bivalve, bryozoan, and coral fossils!

And there’s not just one secret surprise find this time—

found TWO pieces of tumbled uranium glass!

*raises hand* i have no idea what Hell Creak is. tell me more

Hell Creek is a fossil-heavy rock formation located in Montana and North Dakota! It's one of the most complete fossil sites we have of the Mezosoic (along with other standouts like the Morrison and Kem-Kem). Hell Creek gets a few extra cool points for a handful of reasons:

It has a whole host of big name dinosaurs: T.rex, Triceratops, Ankylosaurus, Pachycephalosaurus, Edmontosaurus, and even a large raptor that's a real-life Jurassic Park 'Raptors' (the book and film used oversized Deinonychus, but Dakotaraptor is actually of comparable size. Potentially. I love the species and what it'd mean for the ecosystem, but I don't trust DePalma as far as I can throw him. He accidentally included turtle remains in the holotype, which... come on, man). Another cool big name potentially associated with the formation, but not a dinosaur, is a large Mosasaur species (think a giant marine monitor lizard) that was recently found to exist off the coast, as well as the (potentially) largest creature to ever fly, Quetzalcoatlus (I have no way to describe this, search it up, it's terrifying and weird).

Actually? No. You deserve to see what a Quetz would look like.

(Photo and model credit @bluerhinostudio. Seriously, they're so lifelike.)

Hell Creek's fossils were deposited at the very tail end of the reign of dinosaurs, so you get a look at their last glory days + a good handful of million years prior. Actually, the boundary layer - the actual moment the apocalypse became real and quartz was shocked by the Chixclub impact - is present! There's another site that seems to contain the actual aftermath, with molten glass raining into the mud and debris of animals caught in tsunamis thrown together (though some elements of the site are debated, because DePalma is sketchy as hell and reported different findings to the media vs his publications).

(Credit conveniently included in the image, nice.)

We have SO much information about it! Remains of everything from megafauna and their interactions - herbivores that have healed bitemarks from T.rex, facial bitemarks between T.rexes - to the minute. Pollen and seeds from a host of plants; insects trapped in amber; tiny amphibians, and sharks. The list of species on the Wikipedia articles are absolutely insane - it's so complex and detailed.

There's also a video game in slow, slow development depicting this formation, Saurian - last I heard it's grinded to almost a standstill, and IIRC there is ~tea~ in the paleo community about it, but it was fun following the development for a few years. The concept art is also gorgeous, and you really get a feel for just how much material they have to work with to make this as accurate as possible!

TLDR, Hell Creek is fascinating - though there are plenty of other cool formations worth poking at, too! The Kem Kem Group, Dinosaur Park, Candeleros, Morrison, Jiufotang and Nemegt Formations are all favorites <3

Just now learning about Lightning Ridge in Australia, where opalised fossils are occasionally found. Because I guess fossils just weren't amazing enough already.

These are so beautiful.

9-Year-Old Girl Finds Huge Megalodon Tooth

It took nearly a decade, but Molly Sampson found what she had been searching for her whole life.

It happened Christmas morning when the 9-year-old girl was out searching for shark teeth with family in Calvert Beach, Maryland.

It was there Molly waded into the cold waters of the Chesapeake Bay and pulled out the once-in-a-lifetime find: a 5-inch-long megalodon tooth.

"She was over-the-moon excited," Molly's mother, Alicia Sampson, said on Wednesday. "It was something she dreamt about finding. She's been shark tooth hunting since age 1 when she would crawl along the beach."

A homeschooled student from Prince Frederick, Molly has collected more than 400 shark teeth since before she could walk. But the discovery marked the fourth grader's biggest find yet.

Stephen Godfrey, curator of paleontology at the Calvert Marine Museum, where the girl took her find, confirmed that the tooth belonged to the extinct shark megalodon (Otodus megalodon), which disappeared millions of years ago.

The meg is believed to be one of the largest predators that ever lived until its extinction, and scientists believe it could have grown 50 to 60 feet long. For a long time, scientists believed the megalodon's closest relative was the great white shark, but research shows it is most closely related to the mako shark, according to the Smithsonian.

Field finds today:

1. Shark tooth found in conglomerate. Around Cretaceous in age

2. Cretaceous bivalves, possibly inoceramids

3. Gypsum crystals

All found in road cuts along the side of highways in SE Nebraska and N Kansas

So a couple weeks ago I went to a Geology and Mineral Fair. I bought this fossil shark tooth for $10. The only thing the seller told me was that she found the tooth in Florida.

Obviously the photo is blown up, the crown of the tooth is only 2 cm long (close to an inch)

Tonight (on the spur of the moment) I decided to do some research to see what species of shark it came from.

Doing an internet search, I found the Florida Museum website and they have a w Fossil Shark Guide that includes an extensive tooth ID Key. It’s like a flow-chart, except it’s buttons that help you navigate down the page based on the tooth’s characteristics.

Now, the Teeth Key is loaded with technical terms for the parts of the teeth and descriptions of the teeth. But never fear, there is a glossary! 

They also have a visual guide to tooth morphology at the top of the Guide page.

So after going through the Teeth Guide and the Glossary rather painstakingly, my result was genus Alopia. I did another internet search. Alopia is the genus name for thresher sharks. Prehistoric species of Alopia included the Alopias Grandis, the giant thresher shark. The giant thresher could grow to about the same size as the modern great white, so about 15-20 ft maximum.

I found some photos of Alopia teeth from different species. My tooth is visually similar to the A. Grandis. There is a giant thresher with serrated teeth, A. Palatasi, but my tooth does not have serrations. I am 75% certain that my tooth is that of A. Grandis.

The bottom photo is of A. Grandis teeth found in South Carolina. The bottom right tooth is the most visually similar to my own tooth.
