The non-archosauriform archosauromorph Dinocephalosaurus orientalis was first described from the Upper Member of the Guanling Formation (late Anisian, Middle Triassic) of Guizhou Province by Li in 2003 on the basis of a complete articulated skull and the first three cervical vertebrae exposed in dorsal to right lateral view. Since then, additional specimens have been discovered in southwestern China. Here, five newly discovered specimens are described for the first time, and redescriptions of the holotype IVPP V13767 and another referred specimen, IVPP V13898, are provided. Together, these permit the description of the complete skeleton of this remarkable long-necked marine reptile. The postcranial skeleton is as much as 6 metres long, and characterised by its long tail and even longer neck. The appendicular skeleton exhibits a high degree of skeletal paedomorphosis recalling that of many sauropterygians, but the skull and neck are completely inconsistent with sauropterygian affinities. The palate does not extend back over the basisphenoid region and lacks any development of the closed condition typical of sauropterygians. The arrangement of cranial elements, including the presence of narial fossae, is very similar to that seen in another long-necked archosauromorph, Tanystropheus hydroides, which at least in part represents a convergence related to an aquatic piscivorous lifestyle. The long and low cervical vertebrae support exceptionally elongate cervical ribs that extend across multiple intervertebral joints and contribute to a ‘stiffening bundle of ribs’ extending along the entire ventral side of the neck, as in many other non-crocopodan archosauromorphs. The functional significance of the extraordinarily elongate neck is hard to discern but it presumably played a key role in feeding, and it is probably analogous to the elongate necks seen in pelagic, long-necked plesiosaurs. Dinocephalosaurus orientalis was almost certainly a fully marine reptile and even gave birth at sea.

Dinocephalosaurus was Fully Marine Reptile and Even Gave Birth at Sea, Paleontologists Say
Feb 23, 2024
by News Staff
Paleontologists from Germany, China, the United Kingdom and the United States have described in detail Dinocephalosaurus orientalis, a remarkable marine reptile from the Middle Triassic of China, on the basis of seven beautifully preserved specimens.

Dinocephalosaurus orientalis lived in what is now China during the Triassic period, around 240 million years old.
This aquatic reptile was up to 6 m (20 feet) in length and had an extraordinarily long neck with 32 separate vertebrae.
The animal was very similar to Tanystropheus hydroides, another strange marine reptile from the Middle Triassic of both Europe and China.
“Both reptiles were of similar size and have several features of the skull in common, including a fish-trap type of dentition,” said Dr. Nick Fraser, keeper of natural sciences at National Museums Scotland, and his colleagues.
“However, Dinocephalosaurus orientalis is unique in possessing many more vertebrae both in the neck and in the torso, giving the animal a much more snake-like appearance.”

Dinocephalosaurus orientalis was almost certainly a fully marine reptile and even gave birth at sea.
The exact function of its extraordinary long neck is unclear but it almost certainly aided in catching fish, which are preserved in the stomach contents of one of the specimens.
Despite superficial similarities, the reptile was not closely related to the famous long-necked plesiosaurs that only evolved around 40 million years later and which inspired the myth of the Loch Ness Monster.
“This discovery allows us to see this remarkable long-necked animal in full for the very first time,” Dr. Fraser said.
“It is yet one more example of the weird and wonderful world of the Triassic that continues to baffle paleontologists.”

Dog finds his largest bone ever ...
70 million-year-old dinosaur skeleton discovered by a man walking his dog
Damien Boschetto made the discovery in southern France in 2022.

A man who took his dog out for a walk in France two years ago made an astounding discovery -- one that he's been keeping a secret, until now.
In 2022, Damien Boschetto stumbled upon a massive, 70 million-year-old fossil that turned out to be a nearly complete skeleton of a long-necked titanosaur, he told ABC News.
Boschetto, now 25 years old, said the unexpected discovery was made in the forests of Montouliers, near his home in Cruzy, a village in southern France.

"The territory around Cruzy is rich in fossils of dinosaurs and other species living at the same time," Boschetto told ABC News in a translated statement. "For 28 years, Cruzy has been supplying and building one of the largest collections of dinosaur fossils from the Upper Cretaceous period in France."
Titanosaurs, members of the sauropod dinosaur family, roamed the Earth from the Late Jurassic Epoch -- 163.5 million to 145 million years ago -- to the end of the Cretaceous Period, which lasted from 145 million to 66 million years ago, according to Britannica.
The long-necked dinosaurs are the largest terrestrial animals known, Britannica reports, adding that some titanosaurs grew to the size of modern whales. Their fossils, which include 40 different species, have been found on all continents except Antarctica, according to Britannica.
Boschetto -- who has a "self-taught passion" for paleontology -- discovered the exposed bone fossils, which led to the excavation of a 70% complete, 30-foot-long fossilized titanosaur.

CREATED ON MAY 21, 2024 | 14:52
NÖN editorial team
A sensational discovery was made in Gobelsburg: mammoth bones were uncovered during excavations. Several mammoth bones were recently found in Josef Pernerstorfer's cellar in Rossgraben in Gobelsburg-Zeiselberg, which are described as the find of the century. Originally, only the basement floor was supposed to be leveled, but the impressive remains were discovered. The cellar owner's exemplary reaction led to the Federal Monuments Office being informed.
Bones up to 40,000 years old
Excavations have been taking place since last week under the direction of Hannah Parow-Souchon from the Austrian Archaeological Institute of the Austrian Academy of Sciences (ÖAW). Several layers of mammoth bones were discovered, while stone artifacts point to a time thirty to forty thousand years ago. The charcoal finds enable a more precise chronological classification.
Presumably remains of three animals
The Federal Monuments Office describes this find as a stroke of luck, as the excellent preservation of the material makes modern investigations possible. It is believed that these are the remains of three animals that were found at a depth of 17 meters below the surface.
This spectacular find is unique in Austria in the last 100 years. Next to this excavation is the most famous Venus figurine from Willendorf. The excavations are financed by both the Federal Monuments Office and the state of Lower Austria. The excavations in the Grubgraben are scheduled to continue again in the fall - so it will still be exciting!

‘Virtually complete’ Stegosaurus fossil to be auctioned at Sotheby’s geek week
The 11ft tall and 20ft long fossil, nicknamed Apex, could fetch up to $6m as it’s celebrated as ‘one of the best unearthed’
Rupert Neate Wealth correspondent
Wed 29 May 2024 19.43 CEST
The largest and most complete Stegosaurus fossil ever found is expected to fetch up to $6m (£4.7m) when it is sold as the star lot in Sotheby’s “geek week” auction this summer.
At 11ft (3.4 metres) tall and more than 20ft long the “virtually complete” fossil, which has been nicknamed “Apex”, is more than 30% larger than “Sophie”, the previously most intact stegosaurus specimen which was on display in London’s Natural History Museum.
Cassandra Hatton, the qglobal head of science at Sotheby’s, said: “Apex marks an incredibly important milestone, as simply one of the best fossils of its kind ever unearthed.
“Stegosaurus is one of the most universally recognisable dinosaur species, whose unmistakable silhouette has been a source of fascination and wonder for generations. Through the careful process of excavation, preparation, and installation, Apex sets a new standard for all future discoveries of this magnitude, and further reinforces the enduring appeal of stegosaurus and its vaunted status in popular culture.”
With an auction estimate of $4m-$6m it may become one of the most valuable dinosaur fossils ever sold at auction. The record is held by Stan, a T rex skeleton auctioned off by Christie’s for $31.8m in 2020.
However, the dinosaur auction market was plunged into crisis in 2022 when Christie’s was forced to call off the £20m auction of another Tyrannosaurus rex skeleton, called Shen, just days before it was due to go under the hammer after a well-known palaeontologist raised concerns that parts of the specimen looked too similar to Stan.
