“It’s an area that’s known for producing horned dinosaurs. In fact, there are four other species of horned dinosaurs known from this particular region,” Sertich said. Fossils of the four other species of similar horned dinosaurs with which it shared its habitat were discovered in the same area. Different types of horned dinosaurs have distinct horns along the edge of that frill. “The bodies of these horned dinosaurs are very similar, yet their heads are adorned with some wild head gear.”Similar appendages are found on the heads of horned lizards, Lyson added, except in these horned dinosaurs, they are attached to multiton bodies.

The “exceptional” and “virtually complete” dinosaur fossil, which is 11 feet tall and 20 feet long, will be sold as part of Sotheby’s annual Geek Week. Paleontologists have questioned the sale of such specimens to private bidders, arguing that these finds should be preserved in museums or other public spaces. Nevertheless, that will not stop the auction of the 150-million-year-old fossil from going ahead in New York on July 17. Apex, as it has been nicknamed, is the “finest Stegosaurus specimen to come to market,” Sotheby’s said in a press release Wednesday. It is expected to fetch between $4 million and $6 million, making it one of the most valuable dinosaur fossils ever offered up for sale, the auction house added.

That femur led to a stegosaurus fossil, among the largest and most complete ever found, which has subsequently been nicknamed “Apex.” In July the Sotheby’s auction house will sell Apex at auction at an estimated value of $4 million to $6 million, making the skeleton the latest flashpoint in a long-running debate about the private fossil trade. Dinosaur fossils have fetched escalating prices at auction houses since 1997, when Sotheby’s sold “Sue” the Tyrannosaurus rex to the Field Museum in Chicago for $8.36 million. In 2020, “Stan,” another largely complete T. rex skeleton, sold at Christie’s for $31.8 million. Such pricing has raised serious concerns among academic paleontologists, said Stuart Sumida, vice president of the Society of Vertebrate Paleontology. Many of them have watched fossils that may unlock scientific mysteries get steered into the hands of wealthy private collectors rather than toward research institutions in recent decades.

CNN —A formerly unknown relative of the most iconic of all dinosaurs, Tyrannosaurus rex, has been newly identified, according to a study released Thursday. Called Tyrannosaurus mcraeensis, the creature likely roamed Earth up to 7 million years before T. rex emerged. But Tyrannosaurus mcraeensis’ bones were discovered decades before the creature officially got its scientific name. “The lower jaw in a Tyrannosaurus rex is actually quite robust. “That set the table for when Sebastian started to look at our specimen and say, ‘Hey, these don’t actually look the same as the famous Tyrannosaurus rex specimens from places like Montana.’”

It is the latest legal dispute spawned by Sue, a crown jewel of paleontology regarded as the most complete T. rex fossil ever found. Before her death in 2020, Ms. Williams had written two wills. In a 2017 will, she appointed one of her daughters, Sandra Williams Luther, as the personal representative of her estate. In another will, written in 2020, she designated that same daughter to be her sole heir and the sole executor of her estate.

☆ Birdlike footprints from Triassic mystery animals precede earliest bird fossils by 60 million years

The footprints, found at several sites in southern Africa, were recently identified as the oldest birdlike tracks ever found, preceding the earliest known skeletal fossils of avians by about 60 million years. Some called the tracks birdlike, but others weren’t so sure. Ellenberger may have muddied the waters by assigning many differently shaped tracks to the ichnogenus, “and not all of them are birdlike,” Abrahams said. They could belong to other reptiles or cousins of dinosaurs that evolved birdlike feet,” Clarke said. During a trip to Maphutseng, a fossil locale in Lesotho, the team found a number of birdlike tracks from the Triassic Period.

☆ Up to 1.7 billion T. rex dinosaurs lived on Earth, a new study found. But scientists aren't sure where all the bones went.
▼ + stars: | 2023-05-27 | by ( Erin Heger | ) www.businessinsider.com time to read: +5 min

New calculations suggest that 1.7 billion T. rexes lived on Earth from 65.5-68 million years ago. This dichotomy between how many T. rexes lived and how few fossils we have of them shows us just how rare fossilization is and how much more we have to learn about these majestic creatures. Warpaintcobra/Getty ImagesMarshall was the lead author of an earlier study that estimated 2.5 billion T. rexes once roamed Earth. Of the roughly 1.7 billion, or so, T. rexes who roamed our planet, scientists have only uncovered a few hundred fossils, equating to fewer than 100 total dinosaurs. Despite their prime conditions for fossilization, if Giebeler's calculations are correct, scientists have only found about 0.0000002% of the T. rex that lived on Earth.

☆ T. Rex Had Lizard-like Lips That Covered Its Teeth

Conjure up an image of Tyrannosaurus rex in a Hollywood blockbuster. The meat-eating dinosaur’s long, serrated teeth taper to sharp points that protrude from a gaping maw bared wide in a roar. As the predator closes those jaws around its prey, its upper teeth remain exposed in a fanged smile. But new research is challenging these popular-culture depictions. The teeth of T. rex and its two-legged, three-toed meat-eating kin—known as theropods—were likely covered by thin, scaly lips resembling those of some modern lizards, according to a study published Thursday in the journal Science.

[1/2] The skeleton of "SUE", the Tyrannosaurus rex is displayed at the Field Museum of Natural History in this undated handout picture. Sealed lips would help saliva secretions in the mouth keep teeth, particularly the enamel, hydrated, Cullen said. An examination of the relationship between tooth size and skull size undercut the idea that large theropods simply had teeth too big to be covered by lips. The study identified large lizard species with lips alive today that possess teeth proportionally bigger than T. rex, relative to skull size. In crocs, teeth show asymmetrical wear, with the side of the exposed teeth facing outward more beat up than the inner side.

A large dinosaur footprint left 166 million years ago was found on the British coast. It appears to capture the moment a Megalosaurus-like dinosaur stopped for a rest by the beach. The 3-foot-long footprint, discovered in Burniston Bay, captures the moment the dinosaur stopped to rest by the beach, according to new findings published Thursday. The footprint was likely left by a therapod, a class of two-legged dinosaurs with three toes that includes the Tyrannosaurus rex. The size of the footprint suggests the dinosaur was probably a Megalosaurus between 8 and 9 feet-high at the hip.

The tail’s tip was fortified with bony structures, creating a club that could swing with the force of a sledgehammer. Instead, the pattern looks like the result of receiving a forceful slam from another ankylosaur’s tail club. The Zuul fossil is currently kept in the Royal Ontario Museum’s vertebrate fossil collection.
