T-rex Tooth in the Rough

Yup, a Tyrannosaurus tooth sitting in the matrix. Wrapping it up for the trip back to the ranch headquarters is the next order of business. There it will be cleaned at my leisure when I get a pile of such things to clean so it’s worth setting up the micro-air-abrasive fossil cleaning cabinet. The black enamel of the tooth is etch by tiny rootlets that covered the surface. The chemical reactions at the rootlets deeply marked the enamel of the tooth.

Fossil Teeth: Selective preservation…

Teeth were “plentiful with many per dinosaur. They often broke off, the new ones erupting from below. Shed teeth were called spitters.They were literally spit out or lost eating. Some teeth passed through the digestive system. Quaintly named (sh**ers) by collectors. I’ve been told by older and more experienced paleontologists the way you tell the difference is their taste…… 😜

Here pictured next to the 6 inch wood awl that I used to dig it out of the Hell Creek/Lance Formation quarry wall. I have a 50 foot long by 4 feet thick in the center, river channel filled with mixed debris. This debris was dropped by the river for a reason. The current velocity dropped enough to leave what it carried here, behind. The bigger/heavier things came out first so we find a lot of big bones. The little things concentrated somewhere else with a lower current velocity.

Triceratops Dinosaur Rib Excavation

Triceratops Dinosaur Rib Excavation (Tough Long Read)

There might be a few words to google here. My apologies ⚒⚒⚒. Geology has it’s nomenclatural requirements. To put all this in the big picture is the tough part.

Our Ranch by coincidence 🤔 is located upon a 700 feet thickness of Sandstone. It has exposures of the famous Hell Creek/Lance Formation (Cretaceous Period) The Uppermost Cretaceous was a period of life on a coastal plain similar topographically to the piedmont of North Carolina. Locally the climate was pretty lush, warm and wet. Meandering Huge Rivers choked with Sand / silt worn off the rapidly eroding mountains to the (current) west. The land lay of different orientation that currently.

North America appears to have been rotated 90 degrees west of how it’s positioned currently. Located around the equator with plate tectonics moving/rotating the continent to it’s current position over the intervening 66 million years. T-rex, Triceratops, Duckbills, ankylosaurs, all those dinosaurs kids know the names of lived here. Here one died…

This is higher up rock section toward the top of the Hell Creek formation not long before the massive “Bolide” (google this) struck the earth. Chicxulub Mexico sits on that big impact area. punctuated the extinction process already underway at the end of the Cretaceous. Big 80 percent of all species Extinction events. Extinction ultimately is initiated by a populations inability to reproduce .

There was a pizza oven effect from the radiant heat from all that Bolide ejecta re-entering the atmosphere. That effect didn’t help anything that wasn’t underground or in the water (mammals) as 20 percent of species survived this age. There is a discussion that dinosaur and other groups were waining in density/diversity near the actual time of the Bolide ended the age of Dinosaurs. Dinosaurs as a group died off but avian dinosaurs did not. (Birds are dinosaurs more or less just short tail and teeth). Eventually the environmental effects killed off the food web in the ocean too. Bad time on the planet for most.

SO:

This sediment is called Bentonite. Wyoming sells LOTS of Bentonite. Cooking it turns it white. Lots of industrial uses. Dave Love (a famous Wyoming Geologist) famously wrote/said: “Wyoming is a wonderful State, we can sell our dirt”. 🤘👀⚒ Bentonite is a clay rich volcanic ash as this is a lake deposit. This rib belonged to an animal that floated into a body of water. Spreading of this carcass did occur and one rib bone excavated was vertical as someone stepped on it and pushed it into the mud on edge. I found a raptor tooth mixed in the mud with this 20 percent Triceratops carcass. (It was Dromeosaur richardoestesia )

Above the Triceratops rib is it’s upside down fragment of pelvis. Another rib hides in the upper right corner of the frame. This was one of the smaller ribs collected on a smaller Tric. The little bottles are full of thin superglue which we consume by the pint. We have the tip off the end of it …. A rib like this will come out in 30 pieces and reassembled back at the ranch headquarters.

Cretaceous Ankylosaurus Armor/ Scutes

Kinda looks like just rocks don’t they? “Leaverites” Knowledge is power I point out.

Dinosaurs often had chunks of bone growing on their skin to act as armor. “Osteoderms” are commonly known as Scutes. Many creatures have them. Crocs and Alligators come to mind. Skin surrounded these bony armor chunks They fit tightly in a network of armor to protect the turtle shaped dinosaur with the clubbed /spiked tail from bites. These are remarkably rare. I’ve found these three in 20 years. I’ve found way more T-rex teeth for example and they aren’t exactly growing on trees up here lolol. Ankylosaurs were 20 feet long and 5 foot high at the hips.

Out of curiousity I looked up some pricing on similar items on the commercial market (I have NEVER sold and never will sell a fossil). The smaller one would be in the 500 dollar range and the larger in the 1000 dollar range. I knew they were uncommon but I didn’t know there was a demand for them. Ankylosarids are rare in the upper Cretaceous. Again, they are NOT for sale. They are in the ranch collection of over 10K fossils at this point.

Disclaimer: The Bliss Dinosaur Ranch is 99 percent private land. Deeded ground is the only place it is illegal to collect ANY vertebrate material (if it had a backbone, leave it alone) on public land. BLM, state and Tribal land is off limits. See a turtle shell, leave it lay. On government ground, artifacts from humans are also best left alone. They can definitely get you in big trouble. Invertebrate fossils and wood are a different story. I suggest the Bureau of Land Managements website for further information.

Our ranch is completely covered by the Cretaceous Hell Creek/Lance Formation. Problem is, there is a lot of grass here too lolol.

Dinosaur Dromaeosaur Tooth Serrations

This is a view of a nice tooth on it’s inside concave edge showing clearly the serrations on the edge of the raptor tooth. The serrations weren’t used so much to cut meat but to hold onto meat bitten into. Thusly “ripping” muscle with the neck muscles and the teeth holding on. Rough way to catch fast food. This 66 million year old or so chomper in the mouth of a 8 foot high dinosaur that resembled a bird with teeth and a tail. Most of the rest of the bone structure are very similar to modern birds. The lighter lines on the darker enamel is where capillary roots have chemically etched the tooth’s enamel. This was found close enough to the surface for root action to effect the surface. Another possible explanation is stomach acid has etched the surface of the tooth.

I really enjoy finding nice dinosaur teeth here in the Cretaceous Hell Creek Sands that blanket this ranch. OF the 5 square miles of land we own, MAYBE one acre has fossils on it and there are 25 places that add up to that acre. We do have one bone bed for larger material but this came out of a sandy pit I dug by hand. I find “microsites” sticking in the exposed hillsides that are indeed fossilferous.

Anything that was alive with “hard parts” at the time in the dinosaurs environment is also possible to find. The rivers current sorted fossils by shape weight and size. Thusly concentrating fossils in one spot where the river dropped them. Microsites usually mean small teeth but this honker is an inch and a half long. The glass is 3/16 plate (blue line). That is a glass shelf in my lit display case.

Cretaceous Raptor Dinosaur Teeth

Cretaceous Raptor Dinosaur Teeth: In my “backyard”… Real Big Wildlife, not the little critters we have running around now lolol.

Genuine medium sized T-rex teeth don’t grow on trees. . You don’t find or see these every day up here. We find maybe one every year on average. It’s hard to find them this nice. They are fragile at best plus they aren’t that common. Smaller teeth are more common as there were more smaller animals running around the environment.

The extra image below is a Cretaceous version of “Velociraptor”. It was a Cretaceous relative that paleontologists named Dromaeosaur. Note the serrations and obvious brown enameloid surface. This oak colored preservation is unique to one of my 25 microsites. All other teeth are black here. Again, looks remarkably like a dinosaur tooth. (The squares are an inch on a side). Serrations actively held on to meat bitten into, ripping it away.

These fossils were well preserved even after the owner broke them off. There is still a little bit of the root still attached (the browner part on the left ). The little white lines on the big tooth are chemical etching. This is related to either stomach acid and/or etchings from plant rootlets on the surface of the enamel. The enamel is essentially unchanged since the owner lost it over 66 million years ago.

These are both Hell Creek/Lance formation fossils. I have several of these bigger T-rex teeth . There are many hundreds of smaller other teeth in the ranch collection. These were found over 2 decades of hard work. Interestingly, they ALL to a one look like and actual tooth. Many people mistake rocks with random shapes for teeth. Not many are or were.

Pseudofossils:

I see many NON fossils (fake fossils) on the internet that look like teeth all the time. They are always random shapes of rocks that look like say a tooth… The human mind easily sees shapes in random data. Problem is, they have NO actual substance of a tooth. Most pseudofossils will have NO enamel. No tooth structures internally, no serrations on the edges, nothing that says tooth to a paleontologist. With no microstructure and 3D biology, there is no fossil there.

Pseudofossils may be very interesting and worth picking up. Cool stuff, they just aren’t fossils. These rocks have no biological history in their past thusly are not fossils. .

My background: (I have a masters degree in a Paleontological Field and have been running the Bliss DInosaur Ranch for 20 years. Digging DInosaurs in my spare time.

Dinosaur Vertebral Neural Canal

Looking through a Dinosaur Vertebral Neural Canal in this “Centrum” (vertebra without it’s external processes)

I saw this centrum sitting about in my outdoor rock pile lightly frosted and saw the possibilities lol. The top view is something that not many have seen. The hole is big enough to get your thumb in.

This vertebra was from the lower back area of a Hadrosaur (duckbill) dinosaur. It was found sitting on the surface in the grass at one of my sites. Sometimes all I have to do is walk around and pick stuff up lol. The neural canal was the first information super-highway. Long before fiber optics lolol.

Cretaceous Dinosaurs here in “Cretaceous Country.” Jurassic Park is way older. The End of the Cretaceous was the end of the rule of the dinosaurs over the earth. Those rocks are exposed here on ranch… The Hell Creek/Lance formations here are upper most Cretaceous sands deposited by huge sweeping rivers choked with sand. Bones were like wood then (and as big as branches mostly). Lots of small fossils too are present. Fossils of anything else that was in and around the water are discoverable along with the dinosaur stuff.

Everybody came down to drink sooner or later and was predated. The bones eventually got into the water and covered by fine grained sands and muds pretty quickly. The rivers were dumping sands by the boatload so the soon to be fossil got covered deeply quickly.

The missing processes are a result of being transported by the rivers. Any particular bone might have been buried, then re-excavated by the rivers moving back and forth meandering across the lands. We were just slightly north of the equator at the time. The continent was rotated about 90 degrees from how it is now.

Rule 1 of geology: Processes we observe today, were the same as in the past and will be in the future. Seems logical but some argue with this for what ever reason. I’m good with that.

Triceratops Toe “Phalanx” Fossil

Triceratops Toe “Phalanx” Fossil sees the first light of day in “Some Time” 😜

The latest Cretaceous Age here on the Bliss Dinosaur Ranch was a time of fine grained sediment accumulation deposited from huge rivers. These rivers were sweeping back and forth across the landscape choked by the sand and finer grained sediment load they carried. Sand sized material was the rule for these rivers ability/capacity to carry things down river. This Triceratops Toe “Phalanx” Fossil survived it’s transport from the distant past to the present under my gentle brush.

With the exception of isolated small scale deposits like this, the Hell Creek/Lance Formation is largely barren of fossils. In 5.5 square miles of HellCreek/Lance formation on my ranch, only about an acre can be called ‘fossilferous”. That acre is the total of 25 smaller locations (microsites) and a bone bed Triceratops Toe “Phalanx” Fossil sits here “In situ”. (In place in the undesturbed bedrock).

This fossil is positioned in the outcrop deeper than you might suspect. Your looking at a toe bone physiologically behind a claw/nail. it is 4 more inches deeper into the outcrop so this is the top 2 inches of the bone exposed. Triceratops had big toes lolol. It’s deeper than it is long. I like to take photos of fossils in the outcrop as it’s sort of the “Eureka”/adrenaline rush moment.

Geologic Musings on this ranches “Dirt”:

Geologists consider the Cretaceous to have ended 66 million years ago. This toe bone has literally not seen the light of day in that unfathomable period of time. The sediment it is in, is a mix of sand, clay with chunky chunks (up to 2 feet) of torn up river bottom clays. The ripped up chunks of clay were rounded by bounding down a river/transport. There is a 2 foot thick or so blue clay pure of any fossil or other detritus directly under this 3 foot thick channel. That above that clay is a channel packed with chunks of clay/mud from upstream. . A mix of at least 3 different mud chunks from various sources nearby. I’ve seen chunks of mud angular like they got torn up 50 feet up stream. So this is a “channel” I’ve been following that tapers on either side that filled up with ripped up chunks of upstream river bottom mixed with a variety of bones from who ever was walking around at the time.

The bones were dropped here for me to find because the river waters slowed enough in this location to drop them out of suspension here mixed in among chunks of mud. The spaces between the “Cobbles of mud” are filled with sandy material that “Sifted in” from the flowing water. This is classic river sedimentation/deposit stuff. That is where you find the little fossils too. Sands mixed with smaller rounded pebbles of river bottom clay. It’s all part of the “Bed load” of a river and what is in it depends on river current velocity… (followed by a really long discussion lolol). IF the river is fast enough to move
