How old did dinosaurs get? That is what Drs. Cary Woodruff, me (Dr. Brian Curtice aka Dr. BC), and Dr. John Foster set out to answer on the longest dinosaurs to ever live, sauropods. Previously, the oldest sauropod was a Camarasaurus that came in at 40 years of age, and the oldest dinosaur, the carcharodontosaurid Meraxes, was 50 years old. Results from osteohistologic studies of bones of the 110' long Diplodocus (= Seismosaurus) hallorum from New Mexico and the second Supersaurus vivianae ever discovered, the 120' "Jimbo" from Wyoming shattered the previous records. The big Diplodocus was found to be 60 years old! Although the Supersaurus specimen is likely older still, we unfortunately were unable to determine age because the bone is so remodeled we were unable to gather any evidence of a numeric age, something none of us had ever observed before. It is truly an ancient animal, so old we can't give it a number! Our software analyses conjectured 225 years (!), a number we have no confidence whatsoever in, but is illustrative of how remodeled the bone is.

Weekly forest fact! 🌲 Two redwood species are practically synonymous with California. Along the central, northern coast there are Coastal Redwoods, Sequoia sempervirens, known for their height. On the western slopes of the Sierra Nevada there are Giant Sequoia, Sequoiadendron giganteum, behemoths large enough to drive your car under. But did you know there's a third redwood species? For hundreds of years, botanists uncovered 150-million-year-old fossils of an ancient redwood species across Oregon, Montana, and Idaho. The fossils were so prevalent that Oregon made the Dawn Redwood (Metasequoia glyptostroboides) the state fossil. Analyzing the fossils, scientists believed that the Dawn Redwoods represented an evolutionary predecessor to the two existing redwood species. This was accepted canon until 1939, when Japanese scientist Shiguru Miki discovered a singular living stand of Metasequoia on a remote Chinese hillside in the Sichuan province! The San Francisco Chronicle compared the discovery to finding a living dinosaur and a 20-person expedition was organized to see the trees. After several trips to the site, UC Berkeley professors collected seeds and distributed them to arboretums across the US, as well as Emperor Hirohito of Japan after a personal request. Today, Dawn Redwoods can be found in arboretums and parks from Rhode Island to California. They are often referred to as living fossils. Below are lantern slides from the original expedition. 📷 Photo Credit: UC Berkeley Museum of Paleontology Archives

Rare fossil reveals ancient battle between mammal and dinosaur A remarkable fossil discovery in northeastern China has shed light on an extraordinary event that occurred around 125 million years ago, showcasing a mammal attacking a much larger plant-eating dinosaur. The fossil, found in the Liaoning Province, challenges the conventional belief that dinosaurs had little to fear from their smaller contemporaries. The fossil shows a ferocious badger-like mammal, identified as Repenomamus robustus, engaging in a fierce confrontation with the two-legged dinosaur, Psittacosaurus lujiatunensis. The mammal, about the size of a domestic cat, is shown grappling with the medium-sized dog-sized dinosaur, providing evidence of predatory behavior by a mammal towards a dinosaur—a phenomenon that had not been previously recorded.

A Brazilian scientist has identified Parvosuchus aurelioi, a small crocodile-like reptile that lived 237 million years ago, predating dinosaurs. Discovered in southern Brazil, this rare predator sheds light on pre-dinosaur evolutionary history, highlighting the diversity of life forms during the Triassic Period. #ParvosuchusAurelioi #Paleontology #TriassicPeriod #PrehistoricPredator #EvolutionaryHistory #BrazilianDiscovery #ScientificReports #FossilFinds #ScienceNews https://lnkd.in/gzhtHMui

🎉🦕🎁 Happy Birthday, #Megalosaurus! 🎂🎈🦖 200 years ago today, in 1824, the first dinosaur was taxonomically described by Oxford University's first reader in geology, William Buckland. When the holotype specimen was revealed to the public, Buckland described bones from separate individuals of an, “enormous fossil animal... [with] a length exceeding 40 feet [12m] and a bulk equal to that of an elephant,” (Oxford press, 1824). He incorrectly presumed that Megalosaurus walked on all fours and was "probably amphibious" due to our limited understanding of the animal kingdom. Buckland identified as a natural theologist, and believed that new life forms were continually being created by a higher power, and unintentionally discovered many animals in an attempt to prove God was behind the natural order of the world, and not evolution, as some of his peers believed. In his free time, he was an “intellivore,” or someone who took great pride in expanding their palette to consume almost anything. During his many parties, Buckland was reported to eat mice, puppies, kangaroo, slugs, crocodile, horse, elephant, panther, rotting flesh, poisonous plants, mercury, and even a piece of King Louis XVI’s preserved heart from the museum’s collections. He is widely considered one of the greatest geologists that ever lived due to his contributions to the field, however it wouldn’t be until Richard Owen contributed his own research in 1841 that we would have a name for many of the animals he discovered -dinosaurs. Since megalosaurus’s first appearance to the public, scientists have discovered 1124 additional species of dinosaurs, as well as a myriad of other prehistoric plants, animals, bacteria, and natural phenomena. It’s estimated that between 70 and 90% of all prehistoric life remains undiscovered, and without Buckland’s and Owen’s passion for the natural world, we likely wouldn’t have such an extraordinary foundation for paleontology today! #paleontology #paleoart #art #drawing #dinosaur
