I never let the love for palaeontology die. I might just leave it on my body forever 🦖🌸 #tattoo #tattooideas #tattoodesign #flowertattoo #tyrannosaurusrextattoo #cretaceous #thebesttime #oneday

Its been forever since i've done an Ornithischian. This is Fruitadens. It means Fruita tooth. It lived 152 MYA (Jurassic) in the floodplains of North America. It is 2.4ft (0.73m) long. It is 0.7ft (22.5cm) high and for weight, the paper describing it says 1.1-1.7lbs (0.5-0.75kg) however i estimate it at 4-9.5lbs (2-4kg) (for an animal of its stature, in my opinion i think my weight estimate is better). Fruitadens was a heterodontosaurid, which means it was a small, bipedal, primitive, omnivorous, most likely feathered ornithischian. Premaxillary crowns are small and subequal. The maxillary caniniform is absent (normally present in other Heterodontosaurids). The denticles in the teeth extend farther down than in other species. The dentary caniform has teeth anterior to it that are small, unserrated, and peg-like. Normally in Heterodontosaurids they are conical and the posterior peg-like anterior dentary (if that makes sense) teeth are enlarged. The denrary caniniform is similar in size to the rear dentary (cheek) teeth. Dentary caniniform is unserrated. The maxillary teeth are reminiscent to Echinodon's and Lesothosaurus's. The crowns are low and triangular and expanded. There is no close dental packing. Replacement teeth are present, which is not known in any other heterodontosaurid. The forelimbs are relatively short and the hindlimbs are elongated in the distal sections showing that Fruitadens was cursorial (it be stupid if it wasnt, but ok). 6 sacral vertebrae present and the articular head of the humerus is well developed and hindlimbs habe the same hollowness as small theropods. Fibula is very reduced. It has been tjough that Fruitadens was an omnivore, but slightly more carnivorous than its contemporaries (which are also omnivorous). Fruitadens shows that heterodontosaurids are ecologixal generalists and became less specialized as geological time went on, this aided in their survival being one of, if not, the longest lasting dinossur families. If you have a suggestion for the next dinosaur, please put it in the comment section of this picture.

And this is the last thing you see, once you become aware of the ambush. If you were a Triceratops/Hadrosaur calf, that is. Tyrannosaurus rex had binocular vision, bone-crushing bite, bone-piercing teeth and was at the apex of the Cretaceous food-chain. This specimen is nicknamed “Trix”, and is temporarily exhibited at Cosmocaixa in Barcelona (Catalonia, Spain). It is one of the largest known T rex, and very complete too: only one leg, both feet and arms, dentaries and a few caudal vertebrae are missing from this specimen. A truly beautiful murderbird. #paleontology #paleontologist #paleo #dinosaur #cretaceous #theropod #tyrannosaurus #tyrannosaur #tyrannosaurusrex #trex #trix #trixthetrex #murderbird #science #scientist #specimen #specimens #fossils #fossil #skeleton #skull #teeth #rexy #jurassicworld #jurassicpark #thelostworld

Amber Cretaceous, ~90 million years Sayreville, NJ 3" x 2" x 1" 46 grams collected by me last night. Natural rind with solid amber core, with transparent areas. Working down the rind would produce a fantastic example. The largest sample I have personally seen. Personal communications dince last night have revealed that it is a tremendous size for the locale, and I am struggling to find a larger recorded sample. #cyrminerals #amber #cretaceous #fossil #ancient #cypress #rare #ancientforest #forest #deepseededtadingpost #weirdnj #weirdlyancient

Mammites Nodosoides specimen, circa 90 MYA, Late Cretaceous Mammites is a genus of ammonites which are characterized by their stout shape and beautifully detailed shell designs with clearly defined grooves. They are pretty well distributed with fossils being found in places like the United States to France and Madagascar. PS we have specimens like this for sale on our website too!

South Altantic Ocean formation, Gypsum Mine, Santana do Cariri-CE, Brazil The Araripe Basin comprises a largely Mesozoic intracratonic sedimentary system. During the breakup of Gondwana and opening South Atlantic Ocean reactivation of structures within the Borborema Province resulted in the formation of the Araripe Basin, along with several other sedimentary basins in the north-east region of Brazil. The Cretaceous of the Araripe Basin is divided into seven litostratigraphic units: Abaiara, Rio da Batateira, Crato, Ipubi, Romualdo, Arajara and Exu Formations. The Ipubi Formation is a thick sequence of evaporites composed mainly of anhydrite and gypsum interbeded by bituminous black shales. Currently, studies indicate that the Ipubi Formation was deposited in the Albian (~106 Ma) in lacustrine, anoxic and hypersaline enviroment, showing contribuition of algae and higher plants. 🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸 Formação do Oceano Atlântico Sul, Mineração de Gesso, Santana do Cariri-CE A Bacia do Araripe compreende um sistema sedimentar intracratônico predominantemente mesozoico. Durante a ruptura do Gondwana e abertura do Oceano Atlântico Sul, a reativação de estruturas dentro da Província Borborema resultou na formação desta bacia, assim como várias outras do nordeste brasileiro. O Cretáceo da Bacia do Araripe é dividido em sete unidades litoestratigráficas: Formação Abaiara, Formação Rio da Batateira, Formação Crato, Formação Ipubi, Formação Romualdo, Formação Arajara e Formação Exu. A Formação Ipubi é constituída por uma camada evaporítica composta principalmente por anidrita e gipsita, intercalada por camadas de folhelhos escuros betuminosos. Estudos recentes apontam que a Formação Ipubi foi depositada no Albiano (~106 MA) em ambiente lacustre, anóxico e hipersalino, mostrando contribuição de algas e vegetais superiores. . . . . . . . . . . #geology #paleontology #gypsum #mine #exploration #cretaceous #albian #fossils #brazil #northeastern #deposit #evaporite #rocks #science #ocean #atlantic #south #formation #geologia #paleontologia #gipsita #cretacico #cretaceo #santanadocariri #ceara

Protostega was a genus of sea turtle that lived during the Late Cretaceous Period. Like the modern leatherback sea turtle, its upper shell lacked bony plates, making it lighter and quicker, but more vulnerable to predators. 📷: @annaisrandompics

DINOSAURS. My interpretations of my two faves. I went off the idea that Spinosaurus would have similar colourations to crocodiles etc, and I based the male Parasaurolophus colours of the idea that they used the crest for display purposes. #watercolours #watercolour #art #artwork #artist #ink #dinosaurs #artistsoninstagram #zoology #zoologist #university #dinosaurs #dinosaur #palaeontolgy #animal #spinosaurus #parasaurolphus #cretaceous #jurassic #palaroart

Not sure what the light source is, how to incorporate Morden, where this human came from, or why Bruce is so approachable... but I can't seem to stay away from this underwater theme. #wip #mosasaur #brucethemosasaur #underwater #fossils #reptile #dinosaur #notadinosaur #prehistoric #meetsmodern #exploremb #morden #manitoba #cretaceous #illustration #lakeagassiz #westerninteriorseaway #digitalart #posterdesign #canada #procreate #applepencil #travelmanitoba

[21.02.18] Pour ce cinquante-et-unième jour je vous poste une de mes espèces de fossiles préferées, si ce n'est ma préferée qu'est l'ammonite ! Cette ammonite assez imposante surtout par le poids (c'est lourd les cailloux) est une MAMMITE NODOSOIDES. Elle est originaire du Maroc (coeur sur ce pays rempli de fossiles) et a vécu pendant le Turonien qui est une partie du Crétacé supétieur et donc cette ammonite daterait d'entre -93,9Ma et -89,8Ma. Cette ammonite bien que assez commune la mienne possède une particularité (l'indice est sur la 3ème photo). Et oui à l'intérieur de ce magnifique fossile qui est à moitié cristalisé par ailleurs se trouve un petit cristal de quartz tout mignon. . . . . . . . #fossilhunter #fossil #fossils #fossile #fossilhunt #paleontology #paleo #cretaceous #ammonite #quartz #crystal #gemstone #gem #geo #geology #old #instamoment #instaoftheday #photography #photooftheday #photos #morocco #picoftheday #rock #stone #france #curiosity #collection #dinosaur #animal

When you run out of burlap and it is the last day, you get... Yak Barf! Adapt. Overcome. Improvise.
