This weeks #Lego #FossilFriday is #Camarasaurus
The holotype was found in the late 1800s in Quarry 13 at Como Bluff, Wyoming.
In 1889, Othniel Marsh described it as a new species, Morosaurus lentus
In the 20th century it was found to be the same species as one named by his rival, Edward Drinker Cope.
This resulted in Morosaurus lentus being renamed to Camarasaurus lentus.

🐯🐾🦥🐴🐘🐪 For #FossilFriday, a fantastic mount from the Smithsonian’s National Museum of Natural History’s Hall of Fossils. The Smilodon on display — specimen v10928 — is a composite skeleton, greeting visitors with its wide saber toothed smile.
California’s state fossil, Smilodon fatalis, lived from roughly 400,000 to 11,000 years ago. Every bone in this composite came from the La Brea Tar Pits.

#52wochenfotochallenge Essen & Getränke & #fossilfriday
Heute mal wieder ein spannendes #Fossil aus meiner #Sammlung - ein Kieferfragment vom urzeitlichen #Wal #Basilosaurus 🐋 Anders als moderne Wale hatte er noch kleine Hinterflossen und zwei verschiedene Sorten Zähne im Maul 🦷 Das ist bei der #Versteinerung gut zu erkennen und verrät uns, dass Basilisaurus wohl auch andere Urwale gefressen hat: Dafür spricht die Kombination aus Greifzähnen vorne und dreieckigen Reißzähnen hinten im Maul 🍽️

This week for #Fossilfriday we have another #Guess that #Lego #Fossil.
This one I would rate as easy. This chonker is known from The Jurassic of North America.
Hide your guesses behind a content warning, so others can guess without being spoilt. I will post the answer tomorrow (and to anyone who guesses correctly).

This weeks #Lego #FossilFriday is #Dromaeosaurus
In 1914, Barnum Brown found the first fossils in the Red Deer River formation.
In 1922, William Diller Matthew and Brown named and described the type species of Dromaeosaurus.
Between 1922 and 1988 seven other species were named under the Dromaeosaurus unbrella.
Several of these have since been reclassified as other species or nomia dubia.

For #FossilFriday, shoutout to Spriggina floundersi! It's ~550 million years old, is the first known "righty" animal, and its name so confused my transcription software that it came up with fourteen dubious options (including Spirulina and Sporgeon of Flounder See) 🧪

Eremotherium for #FossilFriday.
This towering giant ground sloth, Eremotherium laurillardi, stands in the Smithsonian’s National Museum of Natural History. Remounted on a custom steel armature during the 2019 renovation of the Hall of Fossils–Deep Time, its external support structure is a piece of engineering artwork in its own right.The animal reportedly contains more than 80% genuine fossil bone and stands 13 feet tall.

This weeks #Lego #FossilFriday is #Anchiceratops
In 1912, a Barnum Brown lead expedition found the first fossils along the Red Deer River in Alberta Canada.
In 1924, Charles M. Sternberg at Morrin found a more complete skull
In 1929, Charles M. Sternberg at Morrin formally described and named the new species Anchiceratops longirostris.

This weeks #Lego #FossilFriday is #Eromangasaurus
In 2005, Benjamin P. Kear named QM F11050 as Eromangasaurus carinognathus.
However, earlier in 2005, Sven Sachs named QM F11050 Tuarangisaurus australis. This name thus take priority over E. carinognathus.
Later studies found Eromangasaurus is distinct enough to be its own species.
In a fun coincidence, Eromanga, means windy plain, locally, but means something very different in Japanese, with Ero meaning R18+ and manga meaning comic.

It's a follow-up #FossilFriday
The mysterious bone fragment I posted about last year has an ID! After examination by the Science Museum of Minnesota, as suspected, the specimen has been confirmed as a mastodon tooth cusp.A simple gravel‑bar discovery has turned into a scientific find — another reminder that Ice Age history is still hiding in plain sight across the Midwest.
If you would you have recognized it let me know.

For #FossilFriday, meet "Junior." I was able to take these photos recently at the new Bison: Standing Strong Smithsonian exhibit in Washington, DC.
Junior is a massive Bison latifrons skull with horns over six feet wide. He was discovered along the Snake River near a reservoir in southeastern Idaho.
Marie L. Hopkins, Idaho's first female paleontologist, excavated Junior and in 1951

This weeks #Lego #FossilFriday is #Huayangosaurus
In 1979-80, partial remains of twelve stegosaurian individuals were found near Zigong China.
In 1982, they were named and described by Dong Zhiming, Tang Zilu and Zhou Shiwu as Huayangosaurus taibaii.
Some replicas show it with a Kentrosaurus style shoulder spike, others do not. I could only find an image of one without.
Original Lego model by Kongzilla, modified by myself to represent a new species.

This magnificent painting by Alan O’Connor now hangs above my fireplace. The holotype specimen of Rhomaleosaurus cramptoni formed the basis for my PhD project 20 years ago. Thanks for the wonderful gift Alan, and thanks for hauling it as luggage this week all the way from Ireland by land/sea/car/train/ferry! 🇮🇪

🐻 For #FossilFriday 🐂🦥🐴🐪🐟 a new #LostBones article is out on Substack! This one is a deep-deep dive into brown bear (Ursus arctos) and giant short-faced bears (Arctodus simus) in the Midwest and Surrounding areas.
Please share to get out the word!

This weeks #Lego #FossilFriday is #Protostega
On July 4th 1871, a Yale College Scientific Expedition, close to Fort Wallace, found the first specimen. Sadly this fossil was never described or named.
About 5 months later, E. D. Cope found and collected the first identified specimen in the Kansas chalk.
In 1872, E. D. Cope named the specimen Protostega gigas.
Several almost complete examples have been found, showing this animal was up to 14 feet long.

While Alberta is better known for its vertebrate fossils, we have plant fossils as well! These are the fossils of the Dawn Redwood, Metasequoia. These plants would have thrived in the Late Cretaceous swamps and deltas that made up the western part of Southern Alberta and provided abundant food for the herds of dinosaurs that made their home in this region. Notably, there's a living species of this genus!

For this Fossil Friday we have the claw bone (ungual phalanx) from a small theropod from the Dinosaur Park Formation in southern Alberta. It’s not clear exactly what species this bone is from but some candidates are Troodon and Saurornitholestes. In life this bone would have been covered in a sheath of keratin, making it much larger!
This specimen was found by Hope Johnson and is APS 2006.071. Photo credit Howard Allen.
