#workinprogress underpainting for #triceratops horridus. Discovered in 1887 by Othniel Charles Marsh, the first bones from this animal were a pair of brow horns attached to the roof of the skull. Marsh originally thought the horns belonged to an extinct species of Bison, that he named Bison alticornis. The following year (1888) Marsh read a paper on the discovery of the fragmentary remains of a horned dinosaur named Ceratops, despite this he still believed that the horns he found came from a bison, later in the same year Jogn Bell Hatcher discovered a more complete skull in Wyoming, dubbing it a species of Ceratops. Marsh corrected his error and renamed his discovery, Triceratops. Triceratops was an herbivore common to what is now North America during the Late Cretaceous (68-66 million years ago), it is estimated to have ranged from around 26 to 30 feet in length and weighed in at around 6.6 to 13.2 tons. Although numerous specimens have been assigned as species of Triceratops, only 2 species are currently recognized by science as being true members of the genus, T. horridus and T. prorsus. In 2014 a study proposed that T. horridus likely evolved into T. prorsus over 1 to 2 million years. In 2010 and 2011 studies by paleontologists John Scannella and Jack Horner proposed that Torosaurus and Nedoceratops, which were thought to be separate ceratopsian species, were actually just stages in Triceratops life cycle with Torosaurus being it's adult form, this has not yet found consensus among scientists, but the research is interesting, however more specimens need to be examined to find a definitive answer. #dinosaur #wip #ornithopod #cretaceous #paleo #paleontology #paleoart #sciart #science #educational #naturalhistory #extinction #extinctanimals #digitalart #digitalillustration #illustration #art #painting #drawing #maine #maineart #newengland #artistsoninstagram

Spinosaurus aegypthiacus Se trata de una versión actualizada de un dibujo que hice hace tiempo, debido al recién publicado artículo de Don Henderson del Museo Tyrrel de Paleontología sobre que Spinosaurus era menos dependiente del agua de lo que se tenía pensado. This is an updated version of a drawing I made some time ago, due to a recently published article by Don Henderson from the Royal Tyrrell Museum of Palaeontology that Spinosaurus was less dependent on water than previously thought. - - - - #spinosaurus #spinosaurusaegyptiacus #dinosaur #spinosauridae #cretaceous #morocco #africa #fossil #scientificdrawing #palaeontology #paleoart

Day 24 of the summer holidays - so this little monkey has somehow stretched his birthday celebrations out over 2 months, and today was a day of dinosaurs! Seeing so many little faces, with eyes open wide with amazement at these creatures makes me wonder where it all goes wrong and people start to lose their amazement and care of the natural world. I couldn’t help but relate the one message that was mentioned throughout the show, how adaptation is the only way of survival, and how this couldn’t be more true for us at this moment in time. To save the Earth from the dangers of plastic, and all the other many issues that it’s facing at the moment, we have to adapt..adapt our way of living to give back to the Earth, and not just take from it, so that the generations after us have the same chance that all those incredible organisms before us had, to be able to continue to evolve and adapt #walkingwithdinosaurslive #familyday #birthdaycelebration #roar #fun #amazing #learning #love #triassic #jurassic #cretaceous #adaptation #versitily #survival #nature #incredible #plasticfree #littlesteps #giveback #save #earthmummy

Happy #fossilfriday everyone! Yesterday we had a visitor from Texas, Mike Olive, an avocational paleontologist from Texas. Mike brought us some cool fossils to look at and help identify. We have some ideas about what this Cretaceous fossil from the Bandera County, Texas area might be, but we’d like to see what all of you think! Any ideas, hive mind? #invertpaleo #fossilsofinstagram #mrolivesmysteryfossil #museummystery #mysteryfossil #avocationalpaleontology #cretaceous #texas #texaspaleontology #banderatexas #fossilidentification #behindthescences #collectionsmanagement #nhmla #howdoyoumuseum

Number 30 The Dinosaurs in the First Jurassic Park Were the First Fully CG Flesh and Blood Creatures Ever on Screen - For the animatronic dinosaurs, Spielberg hired Stan Winston (because of his amazing work on Aliens). Winston built the life-size lizards, including the Tyrannosaurus Rex and Triceratops. Spielberg also hired stop-motion puppeteer Phil Tippett to animate model dinosaurs that would be superimposed in post-production, and Dennis Muren (fresh from creating the molten-metal morphing effects for Terminator 2: Judgment Day) to see if dinosaurs could be created using computer-generated imagery. The dinosaurs Muren created on the computer were the first major flesh-and-blood CGI creatures in movie history. When he screened an early test of wire-frame dinosaurs in motion for the rest of the filmmakers, Tippett realized he was out of a job. “I think I’m extinct,” he told Spielberg, who liked the quip so much that he put it in the movie. In reality, Tippett stayed on as an adviser to the computer animators, using his knowledge of paleontology and pantomime to instruct the effects artists in how dinosaurs should move.

As it’s #fossilfriday I thought I’d share an amazing specimen I saw recently on display at the Museum of the Rockies in Bozeman, Montana. This is the well preserved skeleton of a Tenontosaurus tilletti which was discovered in 1991. Tenontosaurus was a medium-sized herbivorous dinosaur from the early Cretaceous. What’s amazing about this specimen is that 11 Deinonychus serrated teeth were found in association with the skeleton. Although these meat-eating raptors lost teeth regularly (and replaced them), 11 teeth would have been too many to lose on one kill. This suggests that this beast met it’s fate at the hands of a group of meating-eating Deinonychus raptors - ouch!! Amazing specimen which has helped better understand the predator-prey relationship. #museumoftherockies #montana #bozeman #tenontosaurus #deinonychus #predator #predatorprey #dino #dinosaur #dinosaurs #dinosaursofinstagram #raptor #skeleton #skeletonsofinstagram #fossil #fossils #fossilart #fossiladdict #fossillovers #palaeoart #palaeontology #paleoart #paleontology #fossilhunter #extinct #extinction #evolution #cretaceous

“It's a superpredator.” BILLY BRENNAN . Today on Jurassic Blog . Spinosaurus ("spined lizard") was a theropod dinosaur that existed in what is now North Africa during the Cretaceous Period. Spinosaurus is the largest of all known carnivorous dinosaurs, even larger than Tyrannosaurus rex, Carcharodontosaurus, and Giganotosaurus. Estimates published in 2014, and based on more complete specimens, found that Spinosaurus could reach lengths greater than 15 m (50 ft). Its most distinctive feature was the huge sail-like fin on its back. This sail was made from spines that some out of the top of the backbones of all dinosaurs and all other backboned animals. The spines of Spinosaurus, were tremendous: The longest one found was over 1.7 meters (5 feet) tall! The dinosaur may have used its sail to make itself look bigger. If a Spinosaurus turned itself sideways towards an attacker, it would suddenly look much larger, and so the other predator might think twice about attacking. It is also possible that the sail might have been used to show off to attract a mate. . In Jurassic Park . After being cloned and experimented on for a period of 9 months in the late 90's, the unnamed InGen personnel set the dinosaur free alongside the other illegally bred dinosaurs. It was the largest carnivorous dinosaur on Isla Sorna. Being created illegally and against the knowledge of InGen or Masrani higher ups, it is unknown if the Spinosaurus and the other new dinosaurs were affected by or were even bred to include the lysine deficiency that affected the original dinosaurs. There is only one individual known to have lived on the island. It took residence in the jungles of the northeast and became the apex predator of the region. .

Liopleurodon. ©DeviantArt ~©Paul Carter (Carnosaur) ~©Stalio ~©Olorotitan ~©crazycolleeny ©www.prehistoric-wildlife.com . Got requests? . 🚨INFORMATION🚨 . ~Liopleurodon (pronounced /ˌliːoʊˈplʊrədɑn/, meaning 'smooth-sided teeth') is a genus of large, carnivorous marine reptile belonging to the Pliosauroidea, a clade of the short-necked plesiosaurs. Two species of Liopleurodon, L. ferox and L. pachydeirus, lived during the Callovian stage of the Middle Jurassic Period, while the third, L. rossicus, lived during the Late Jurassic. It was an apex predator of the Middle to Late Jurassic seas that covered Europe.~ . ~Four strong paddle-like limbs suggest that Liopleurodon was a powerful swimmer. Its four-flipper mode of propulsion is characteristic of all plesiosaurs. A study involving a swimming robot has demonstrated that although this form of propulsion is not especially efficient, it provides very good acceleration - a desirable trait in an ambush predator. Studies of the skull have shown that it could probably scan the water with its nostrils to ascertain the source of certain smells.~ . ~The largest known Liopleurodon skull belongs to L. ferox. It measures 1.5 meters long and was originally estimated to belong to an animal about 10.5 meters (34 feet) in length.~ . ~A mandible on display in the Oxford University Museum of Natural History, estimated to be over 3 meters and to have come from a skull perhaps 3.6 meters in length, was at one time classified as Liopleurodon macromerus.~ . ~The discovery of a very large pliosaur was announced in 2002, from Mexico, nicknamed the 'Monster of Aramberri'. A cautious estimate placed this juvenile at about 15 meters (49.2 ft) long. It was widely reported as belonging to Liopleurodon, however no taxonomic conclusions could be made due to poor preservation and fact that the remains were of a partial vertebral column.~ . . . #dinosaur #dinosaurs #triassic #cretaceous #carnivore #jurassic #herbivore #omnivore #paleobiology #paleontology #prehistoric #park #world #pangea #grasslands #desert #rainforest #forest #tundra #holocene #pliocene #pleistocene #miocene #oligocene #eocene #paleocene #mammals #prehistoricgram #animals

Uppermost Cretaceous Hell Creek amber (Maastrichtian, ~ 67 million-year-old) in matrix (Hell Creek fm., Harding County, South Dakota, USA) | #amber #fossils #bernstein #fossilresin #cretaceous #cretaceousperiod #palaeontology #paleontology #geology #fossilfriday #hellcreek #hellcreekformation #southdakota #usa

lanzhousaurus magnidens is perhaps most notable for its "astonishingly huge teeth", among the largest for any herbivorous creature ever, which indicate it is a styracosternan iguanodont. The mandible, longer than one meter, suggests very large size for the animal. Tooth enamel of this dinosaur was growing very rapidly. · · · · #dinosaur #dinosaurs #dinosaursofinstagram #dinosaurfossil #fossil #fossils #fossiladdict #museum #museums #museumaddict #fossillovers #nature #cretaceous #earlycretaceous #barremian #learnsomethingnew #knowledgeseeker
