Raccoon Fossil Premolar and Molar Teeth - Florida - Pleistocene

[mindblowingscience]

Ever wondered why our teeth are so sensitive to pain or even just cold drinks? It might be because they first evolved for a very different purpose than chewing half a billion years ago, a study suggested Wednesday. The exact origin of teeth—and what they were for—has long proved elusive to scientists. Their evolutionary precursors are thought to be hard structures called odontodes which first appeared not in mouths but on the external armor of the earliest fish around 500 million years ago.

It's been a while since I posted any new creek finds! There have been a LOT of neat ones lately so instead of my usual small "plate of forbidden snacks" photo layout I just arranged a few of them on a tabletop.

Pictured are: deer skull, deer jawbone, cow teeth, horse tooth, muskrat tooth, deer toe bone, old toy car, a really neat toy boat from the 1970s/80s, an old melted milk glass marble, weird little iron concretion, a cute little yellow tile, nice chonky pieces of bonfire glass, a rainbow of pretty tumbled bits of old pottery, china, and glass, a cow ear tag, and oodles of crinoids, brachiopods, bryozoans, and other neat fossils.

Also found: someone's checkbook (empty), old cellphone (found a couple of those down there lately), Great White "Once Bitten" cassette tape, and Melissa Forney's "Pizzazz: Songs for the Writing Classroom" CD lol.

And there are FOUR special secret finds:

Three bits of uranium glass and an old piece of china that lights up under the black light too.

Fossil Shark Teeth ID Project - Part 8

I am currently working on a shark teeth ID project. It is a personal project I am working on because I got gifted a multitude of fossil shark teeth of various species.

These are shark teeth ID#051 - ID#060. If I misidentified anything, or if anyone has any questions or wants to be tagged in this project, please let me know:)

ID#051

Species - Scientific Name: Striatolamia macrota - Striatolamia macrota

ID#052

Species - Scientific Name: Porbeagle shark - Lamna nasus

ID#053

Species - Scientific Name: Porbeagle shark - Lamna nasus

ID#054

It's been a while since I posted some creek finds! A LOT of really neat little treasures have washed up recently. Here are a few of them!

On this plate of creek finds we have 5 and 1/2 cow teeth, a goat or sheep tooth, opossum tooth, rabbit tooth, an old button, probably my favorite brachiopod fossil I've ever found (it's solid white quartz!!), some really exceptional crinoid fossils, first gastropod fossil I've ever found down there, loads of other rad fossils, some tumbled pieces of soda bottles from the late 1800s or very early 1900s, a piece of an old crock butter churn, lots of other neat tumbled glass and pottery pieces, some nice quartz crystals, a 25 year old plastic toy from Burger King lol, and maybe my favorite piece on the plate—a bisque porcelain duck head from an old figurine.

Amidst all of these awesome treasures there is also a special secret find—

It's another nice little chunk of creek-tumbled uranium glass! Looks like part of an old candy dish.

Dentist Discovers Human-Like Jawbone and Teeth in a Floor Tile

While touring his parents' recently renovated European home, a dentist spotted something unsettling. Embedded in a travertine floor tile along the hallway leading to the terrace was what appeared to be a human jawbone. Sliced diagonally, the tile revealed a cross-section of several teeth. Uncertain of the proper course of action, the dentist turned to Reddit, where the discovery ignited a frenzy of online interest, ranging from enthusiastic curiosity to sheer disgust.

The discovery has captured the attention of an international team of scientists who are eager to examine the fossil. They believe it could belong to an extinct human ancestor.

"If it turns out to be a fossil hominin, which I think it is, it should be studied and placed in a museum," John Kappelman, an anthropology professor at the University of Texas at Austin who specializes in hominid and hominin origins and evolution, said in an email.

Travertine, a type of limestone commonly used in construction due to its aesthetic appeal and longevity, often forms near mineral springs and can contain fossilized remnants of past life. While plant, algae, and even animal fossils like those of rhinos and giraffes are occasionally found in travertine, human remains are exceptionally rare, as noted by University of Wisconsin paleoanthropologist John Hawks, Forbes reported.

In a blog post titled "How Many Bathrooms Have Neanderthals in the Tile?" Dr. Hawks highlights the uncommon nature of this particular discovery.

"I expect there will be many twists and turns in the story of this jawbone," Mr Hawks wrote. "With some teeth preserved and abundant surrounding rock, I expect that specialists will be able to learn a great deal about the life of this individual and when he or she lived."

The European dentist, who specialises in dental implants, told Forbes that he immediately knew he wasn't just looking at stone tile's natural pattern variations when he saw several teeth staring up at him.

"From my dentist's point of view I had no doubt it was some kind of human," he told Forbes. "The teeth distribution and size of the mandible is characteristic. Also, the width of the cortex is specific to ancient humans."

"I don't think it is Jimmy Hoffa," the dentist joked in a follow-up to his original Reddit post. He said he prefers not to reveal his name, or his parents' location, to protect the family's privacy.

When the dentist spotted a jawbone as part of his parents' home upgrade, he was surprised for a different reason.

It is very, very unusual to find vertebrate fossils in processed travertine tile, and hominin fossils 100 times more so," Kappelman said. "We have only a handful."

Mr Kappelman was part of a team that observed the earliest evidence of tuberculosis etched on 500,000-year-old human skeletal remains discovered by factory workers in Turkey cutting travertine tile for commercial use. The scientists published the findings of their research in 2007 in The American Journal of Physical Anthropology.

A new analysis of Viking-era teeth – dating back around a thousand years – has given us some interesting insight into the dentistry of the time, which looks to have been more advanced than previously thought. Researchers from the University of Gothenburg and the Västergötlands Museum in Sweden looked at a total of 3,293 teeth from 171 of the Nordic marauders, including both kids and adults. Modern-day dentistry assessments were carried out on the teeth, including the use of X-ray scans and dental probes, and it turns out that these Scandinavians didn't just leave their teeth to rot and decay.
