SISTER FORMATIONS: MORRISON, LOURINHA AND TENDAGURU

Back in the Late Jurassic Period, North America, Europe and Africa were next door neighbors.

This is reflected in the similarity of the lithology, and fauna of the rocks. In North America, we have the Morrison Formation, in Europe we have the Lourinha Formation, and in Africa we have the Tendaguru Formation. All of these are contemporaneous or sister formations.

Stratigraphy

The Tendaguru Formation is approximately 177 m thick and broken up into five members: Lower Dinosaur Member (cross-bedded, fine-grained sand and siltstone w/interbedded clay), Nerinella Member (trough cross-bedded and massive sandstone indicating a tidal channels, sandbars and beaches),

Middle Dinosaur Member ( ripple, cross-bedded, fine-grained calcareous sandstone and siltstone and massive to crudely bedded siltstone and claystone indicating tidal flats and lagoons),

Indotrigonia Africana Member (calcite cemented sandstone, conglomerate, thin claystone, and siltstone with sandy limestone indicating tidal and deltaic channels),

and the Upper Dinosaur Member (ripple, cross-bedded, fine-grained sandstone and siltstone with interbedded claystone and micriitic carbonates indicating tidal flats).

The Lourinha Formation is about 200 to 1000 meters thick and is broken into about 5 members: Praia da Amoreira Member (massive mudstone with meter thick sandstone lenses and calcrete layers indicating a meandering river system),

the Porto Novo Member (cross-bedded sandstone indicating a deltaic system), the Praia Azul Member (marl and mudstone indicating brief marine transgression),

and the Santa Rita and Assenta Members (mudstone, caliche, shelly carbonates near the top indicating a landward side of a deltaic system) which are equivalent members from different basins.

The Morrison, as stated previously, is about 200 m thick and consists of 11 different members. I will not go into detail about them again but it should be noted that the formations are approximately the same thickness and made of primarily sand, silt and mudstone.

DINOSAURS

Now for the other fun part: the dinosaur fauna. There are some dinosaurs that are shared between two or all of the formations. These include Ceratosaurus nasicornis in the Morrison and a possible Ceratosaurus in the Tendaguru

and in the Lourinha, Torvosaurus tanneri in the Morrison, Torvosaurus gurneyi in the Lourinha, and a possible Torvosaurus species in the Tendaguru,

Allosaurus fragilis in the Morrison and Allosaurus europaeus in the Lourinha,

Dryosaurus altus in the Morrison and a possible Dryosaurus species in the Lourinha,

Miragaia longicollum in the Lourinha and possibly Miragaia longispinus in the Morrison. Though if that's true, the genus would be Alcovosaurus because that was named first.

And then there are the dinosaurs that were similar to each other in each formation. Filling in the niche or living alongside Dryosaurus was Dystalotosaurus of the Tendaguru,

Eudryosaurus in the Lourinha, and Nanosaurus in the Morrison.

There's Draconyx in the Lourinha and Camptosaurus in the Morrison as early iguanodonts.

Kentrosaurus in the Tendaguru, Dacentrurus in the Lourinha and Stegosaurus and Hesperosaurus in the Morrison are the main stegosaurs.

For ankylosaurs, there is Dracopelta in the Lourinha and Mymooropelta and Gargoyleosaurus in the Morrison.

Then there's Dicraeosaurus of the Tendaguru and Suuwassea of the Morrison.

Giraffatitan of the Tendaguru, Lusotitan of the Lourinha and Brachiosaurus of the Morrison all represent brachiosaurs.

Janenschia of the Tendaguru and Haplocanthosaurus of the Morrison represent early sauropods.

Tendaguria of the Tendaguru and Zby of the Lourinha are even earlier sauropods.

Torneiria of the Tendaguru and Deinheirosaurus of the Lourinha are the diplodocids that match up with the bagillion in the Morrison.

Lourinhasaurus is the camarasaurid representative of the Lourinha.

The Tendaguru and the Lourinha have early carcharadontosaurs in the forms of Veteruristisaurus and Lusovenator.

Lourinanosaurus is the European equivalent of Marshosaurus in the U.S.

And Elaphrosaurus of the Tendaguru is the small to medium-sized equivalent of Tanycoalgreus in the Morrison.

This was a ton of info so if you want it more broken down, message me! I am happy to walk you through it all! Enjoy your weekend!

Patreon request for @/rome.and.stuff (Instagram handle) - Saurophaganax maximus

Saurophaganax maximus was an allosaurid from Late Jurassic Oklahoma, USA. Reaching 10.5 metres (34 ft) in length and weighing 2.7–3.8 metric tons (3.0–4.2 short tons), it was the largest terrestrial carnivore in North America during the Late Jurassic, bigger than both its contemporaries Torvosaurus tanneri and Allosaurus fragilis. Some scientists argue that it was in fact a species of Allosaurus (making it “Allosaurus maximus”), but possible Saurophaganax material found in New Mexico may shed light on the genus. With a name meaning "lord of lizard-eaters", it was likely the apex predator of its environment.

Found in the Brushy Basin member of the Morrison Formation, Saurophaganax would have had a multitude of prey species to choose from. These ranged from small ornithischians like Camptosaurus, Dryosaurus, and Fruitadens, armoured thyreophorans like Gargoyleosaurus, Mymoorapelta, Hesperosaurus, and Stegosaurus, to a diverse array of giant sauropods like Haplocanthosaurus, Amphicoelias, Apatosaurus, Brontosaurus, Barosaurus, Diplodocus, Kaatedocus, Supersaurus, Brachiosaurus, and Camarasaurus. Small theropods included Coelurus, Hesperornithoides, Tanycolagreus, and Ornitholestes.

The Morrison didn’t only have a large diversity of dinosaurs. Many pseudosuchians lived alongside Saurophaganax, from the skittering, long-legged Hallopus to the more aquatic Amphicotylus. Pterosaurs were uncommon but widespread, and included rhamphorhynchids like Harpactognathus and ctenochasmatids like Kepodactylus. Other reptiles like rhynchocephalians, lizards, basal snakes, and turtles were common as well. Many cynodonts, mostly early mammals, also called the Morrison home.

The Morrison Formation was also rife with other large predators that could have been either competitors or prey to Saurophaganax themselves. These include the previously mentioned Allosaurus and Torvosaurus, as well as the smaller Ceratosaurus nasicornis and Marshosaurus bicentesimus. As Allosaurus seemed to be the most numerous predators in this formation, they may have been successful pack hunters while Saurophaganax was more of a “lone wolf.” Its remains are much rarer than that of its smaller, lither cousins, and it was likely an opportunistic scavenger and hunter, needing much more food to power its larger frame.

Amphibious Ceratosaurus design for a friend's project about mutant dinosaurs.

The Ceratosaurus present on the tour have garnered a nasty case of hunchback posture due to their ambush-dependent life style, which proves to be effective with their sabre-esque teeth piercing the vital areas of vulnerable meals. Fortunately this mutation is subsided by their adaptive ability to swim in rivers, lagoons, and other bodies of water. Their frog-like coloration allows for camouflage in sun-tinted waters, preventing fish and other dwellers from noticing such a behemoth. Each Ceratosaur is armed with webbing in between their toes, allowing for a more powerful kick through their aquatic territory.

---- Artist Commentary ----

Wooo, this was a fun design, terribly sorry for the lack of proper art in my recent posts. I've been backed up with college and work, but I finally got this design to (digital) paper! The design was a mix between retro and modern depictions of Ceratosaurus nasicornis, featuring pebble like skin, a hunched posture, along with a lean frame as seen in modern reimaginings of the Morrison Menace. There's also the inclusion of the preposterous aquatic ceratosaur theory to give it that slightly bizzare edge.

Made myself a little "personal taxonomic ranking" card because I am a nerd and wanted to make something fun related to my identity.

It's also a handy little visual for the way this particular set of identities nest within each other.

Image ID and more description below the read more!

Basically:

Domain is standing in for the broadest sense, the "Who I Am" rather than "What I Am".

Kingdom would be Alterhuman in this case. Of course there are other "Kingdoms" that make me what I am, but we're focusing on this one and narrowing down the exact identity from there.

Phylum narrows down to an important determining factor of this alterhumanity. I identify as, not identify with, which puts me into a different category (and if I identified with instead of as, that would open up other categories as well!).

For Class, the question is, do I identify as some sort of alterhuman human (such as some fictionkin) or do I identify as something non-human? Since I identify as something non-human, that would be my personal taxonomic class.

Order is where we get more detail. I don't identify as humanoid so non-humanoid is the order I am in!

Now for Family, this is where we get into some of the labels where you would find Otherkin, Therianthrope/Therian, Folcintera, Stelliferoforme, Fictherian, and other more narrow identity terms. Once upon a time, you'd have found me in otherkin or therian, but I feel the term I have in this essay, stelliferoforme, is a better fit to describe my identity.

From there we get what type of stelliferoforme I am and that's where my "Ceratocorvus" (also the name of the innerworld and system) comes in, since I am equally a ceratosaurus and a raven in this identity. And then the species name because, again, I'm a nerd.

My dinosaur OC called, Psychoticus rex

It is a hybrid of Tyrannosaurus rex, Giganotosaurus carolinii, Carnotaurus sastrei, Ceratosaurus nasicornis, and Allosaurus fragilis.

Standing up to 27 feet tall, measuring up to 53 feet long, and weighing up to 47,000 pounds, it is the largest carnivorous dinosaur that ever existed.

It is a carnivore, meaning it eats everything that moves, including humans. It is a apex predator meaning it had no natural enemies, although the T. rex, the Spinosaurus, and the Giganotosaurus were the competitors of the P. rex.

He’s no generic predator since he does have a personality. He is tyrannical, malevolent force of nature, meaning he is a truly sadistic beast capable of showing no empathy. Kills random creatures, including dinosaurs and mammals, not for food, but for pure sadism.

The Psychoticus rex is nevertheless responsible for multiple genocides of humans, dinosaurs, and other animals, because he attempted to destroy and conquer the entire island.
