All Work and No Play

Makes Frank a Dull Boy of course. I was cruising the back woods of the Bliss Dinosaur Ranch and came upon these two titans fighting for dinner. One wanting dinner and the other not wanting to be dinner. Not to be one to intrude on important negotiations, I just too the image.

Since Triceratops is found in the fossil record at over 50 percent of the fossil content and T-rex only at 3 percent, conclusions: There were 15 times the number of Triceratops walking around than there were T-rex. We don’t know for sure if Triceratops herded as a group. A group/row of nose, brow and shield horns were formidable but not a match for the speed and power of the bird like predator.

I say bird like because T-rex was a member of the dinosaurian raptorian group. You may remember Velociraptor from Jurassic Park the movie. T-rex is related to the “Avian Dinosaurs” in many ways. They are often drawn now with feathers in patches by educated paleontologic artists. Bone structure, the way the bones fit together, their respiratory system are all very very very birdlike…

Dinosaurs didn’t die out at the end of the Cretaceous as is widely believed. The avian dinosaur lived on slowly loosing tail and teeth developing into those familiar birds flying about our skies. Occasionally those repressed gene will express itself and say a hen will get teeth. The tail is in the chickens genes too. It’s a matter of proper timing during embryonic development. Any doubt, just watch a Great Blue Heron Hunt….

We actually do have dinosaurs up here but they aren’t moving very fast. The Cretaceous Hell Creek/Lance formation(s) are dinosaur fossil rich. Not JUST dinosaur here of course. There are fossils of snails, clams, amphibians, fish, crocs, alligators, turtles and even a few small mammals represented in these old terrestrial river sands. Currently the ranch collection holds in excess of 10K fossil specimens.

(Note just so you know, Grass during the dinosaur era was JUST developing in India first during the Cretaceous. It spread around the world but not untill later. They didn’t have bamboo forests)…

Triceratops Toes Composite

Triceratops Toes Composite (Real Wildlife)….

There are 19 bones in the toes of “Triceratops horridus” . These toe bones are each a separate animals contribution to this composite assemblage. All approximately the right sized toe bones properly place to assemble those toes to scale. Our Ranch sits entirely with the Dinosaur Fossil rich Hell Creek/ Lance Formation at the surface. The 66 million year old/Cretaceous Terrestrial Sandstone Formation is not abundantly fossiliferous but I’m sure there are several animals around here. The trick is seeing them through the rock. Each and every bone I find promotes an adrenaline filled EUREKA moment. I’ve been a student of paleontology since I was 5 years old with my first EUREKA moment. 🤔🤣

Each one of these individual bones was a separate excavation at different times and 3D place in the outcrop. None of these belong to the same Triceratops. It took a few years and a little work to gather the bits and pieces for this assemblage. Several of the pieces show repair, a few are as found broken/cracked. Stabilized all with a diluted superglue compound. (Paleobond or Starbond). Soaking into the porous bone, the capillary action wicks the thin cyanoacryilate stabilizing the fossil. Deposition occurred long before the Big Horn Mountains rose from the earth. 130 miles to their west. The River that transported these bones also carried sand from Mountains long gone now. Mountains come, and mountains return to the sea as sand carried down by the river.

The hooves/claws/fingertips are the RARE bones but I indicate that just “plain old” Triceratops toe bones don’t grow on trees anymore lololol. Particularly pretty well preserved ones. This particular fossil site providing these is a wonderful place. 📸

Table below is an Eocene lake bed from Kemmerer. The whole table has several fossil fish on it but that’s not the focus for this post. You can see a partial on the lower left corner and a tail on the far right. The white spots are cuprolites. For a Scale I used an 18 inch ruler. The table weighs about 400 pounds. It rolls well on it’s side though. 🤣👀

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.

Triceratops Horn and Frank Bliss

Triceratops Horn and Frank Bliss

Happy New Years Day. I don’t take many Selfies. Maybe 5 or 6 a year. I just thought I’d be a scale for this brow horn from a rather large Triceratops horridus. Triceratops is the Wyoming State fossil but I bet a few more have been found in Montana. This one was pretty much right on the border give or take a few hundred feet.

Obviously the horn is missing the tip with was either “broomed” prior to the animals death or damaged during river transport. The Hell Creek/Lance formation covers our ranch entirely. Unfortunately for the fossil collector in me, most of that is covered by grass. The initial discovery fossil from the site this horn came from was literally sitting in the grass. Located on a shallow hillside, this site has given me over 30 Triceratops Horns, dozens of teeth, toes, claws, spines, scutes and other wise a pile of pretty well preserved dinosaurian bones.

Take my work on this being a horn, somebody out there will think it’s a limb bone missing the condyle end. Nope. It’s a horn. I’ve collected over a dozen just like it. It’s the 3-D nature of the fossil that gives it away. Horns have very characteristic surfaces and this one has veinous grooves with the proper interior of a horn. Shape is Seldom the defining characteristic of a fossil. There are many rocks that look like fossils (pseudofossils) but aren’t. This is a 66 million year old horn from a big Tric. I also have over a dozen nose horns. Thus naming my bone quarry the “Horn Sieve Site”.

Triceratops Toe “Phalanx” Fossil

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
