Curious by nature. Background in applied linguistics and genetics. Thinking about data protection and AI, while loving travel, anthropology, history, archaeology — plus a soft spot for dinosaurs. Email: dalvarez.bsky@gmail.com
A new addition to my fossil collection—this time from North America. A tiny Elrathia kingii trilobite from Utah, dating to the Middle Cambrian (~500–510 million years ago). #Paleontology #Trilobite #Cambrian #Fossils
This is a reconstruction of a titanosaur embryo based on one discovered inside a fossil egg in Argentina. Rare finds like this have helped scientists understand dinosaur reproduction. #Paleontology #Dinosaurs #Egg
A beautifully preserved fossil crab (Avitelmessus grapsoideus) from the Late Cretaceous (~70 million years ago), discovered in the Ripley Formation of Mississippi. On display at Denver Museum of Natural and Science. #Paleontology #Fossils #Cretaceous #Science
A 50-million-year-old fossil palm from Wyoming. This ancient palm would have stood about as tall as me. Even traces of insect feeding are preserved on the leaf—a remarkable snapshot of an ancient ecosystem. #Paleontology #Fossils #Paleobotany #Eocene
1/2 Triceratops horridus skull on display at the Denver Museum of Nature & Science. One of the most iconic ceratopsian dinosaurs from the Late Cretaceous (~67 million years ago), Triceratops combined formidable cranial ornamentation with a herbivorous lifestyle. #Dinosaurs #Triceratops #Fossils
A beautifully preserved straight-shelled cephalopod (orthocone) embedded in limestone. I love having fossils in my hands and being able to touch them. #Fossils #Paleontology #cephalopod
A giant ammonite in the storage collections of the Utah Field House Museum. Not every fossil ends up on display—museum collections preserve countless specimens for research and future study. #Fossils #Ammonite #Paleontology #Museum #NaturalHistory
Allosaurus skull! One of the top predators of the Late Jurassic, this impressive skull is on display at Dinosaur National Monument. It once roamed the Morrison Formation around 149 million years ago. #Allosaurus #Paleontology #Fossils #Jurassic #Dinosaurs
A weathered Utah juniper (Juniperus osteosperma). Even after dying, these slow-growing trees can remain standing for decades in the dry climate of the American Southwest, providing habitat and gradually returning nutrients to the ecosystem. #Trees #Botany #Nature #Desert #TravelPhotography
Mammoth tusks! These incredible Columbian mammoth tusks, discovered in Colorado. They date to the last Ice Age, before mammoths disappeared around 11,700 years ago. Seeing them in person is amazing! #Paleontology #Fossils #Mammoth #IceAge
1/2 I couldn't resist buying this beautiful fossil. A beautifully preserved Knightia from Wyoming's Green River Formation, around 50 million years old. #Fossils #Paleontology #Fish #Wyoming
Somewhere in Colorado there is a town called Dinosaur.... #Dinosaur #Colorado #Roadtrip #Travelphotography
1/2 A giant Jurassic ammonite I was lucky to see in the collections storage of the Utah Field House of Natural History State Park Museum—not on public exhibit. #Fossils #Ammonite #Paleontology #Jurassic #Museum
These are original Diplodocus longus teeth from the Late Jurassic, about 149 million years old, found in the Morrison Formation. Amazing how these teeth have survived for nearly 150 million years. Photo taken today at Dinosaur National Monument, Colorado.
Not all dinosaur fossils are equally impressive. This is the right femur of an adult Camarasaurus, a 149-million-year-old giant from the Jurassic Morrison Formation. I took this photo today at Dinosaur National Monument in Colorado. #Dinosaurs #Jurassic #Paleontology #Fossils #Colorado
Thank you so much. In the Museum here they display items from the time.
Ancient squids like Endoceras lived in Manitoba during the Ordovician Period. Unlike most modern squids, they had external shells that could grow up to 3 metres long. A representation of what they might have looked like when alive is in the link below. #Fossils #Paleontology #NaturalHistory
Apsopelix anglicus, a Cretaceous fish from Kenville, Manitoba. Fossils like this provide a glimpse into the marine ecosystems that covered much of central North America around 80 million years ago. #Fossils #Paleontology #Cretaceous #NaturalHistory #Museum
A beautiful traditional Indigenous cradleboard with intricate floral beadwork and embroidery. #Indigenous #IndigenousHistory #CulturalHeritage #Embroidery
Head of the replica of Bruce, the largest mosasaur ever discovered. An incredible sight at the Canadian Fossil Discovery Centre. #Mosasaur #Paleontology #Fossils #Manitoba
A reconstruction of the Late Cretaceous mosasaur Suzy. The articulated skeleton is suspended above, while the original fossil bones are displayed in the cases below. #Paleontology #Fossils #Mosasaur #Science #Museum
A 12-metre-long Styxosaurus that swam in the Western Interior Seaway 80 million years ago. Its neck made up almost half its body length, helping it hunt fish with spear-like teeth. Close-up photo of the head in the second post of this thread. #Fossils #Paleontology #Styxosaurus #Manitoba
The fossil of a pliosaur, laid out almost exactly as it was found. The remarkable preservation of the skull and jaws contrasts with the rest of the skeleton, which was scattered by currents and scavengers. #Paleontology #Fossils #Pliosaur #Sharks
The largest trilobite ever found: Isotelus rex. This specimen is 72 cm long. I finally saw it! 😀 Photographed today at the Manitoba Museum in Winnipeg. #Trilobite #Fossil #Paleontology #Evolution #ManitobaMuseum
This is how a Neanderthal would likely have looked. Photographed at the Museum of Human Evolution in Burgos, Spain. #Neanderthal #HumanEvolution #Prehistory
