[ Argentinosaurus, a giant sauropod, illustrated by Chase Stone. ]

"Of all the animals ever to have roamed the planet, the iconic long-necked, long-tailed dinosaurs known as sauropods stand unrivaled. No other terrestrial creatures have come close to attaining their colossal sizes. They overshadowed all other dinosaurs, from the duck-billed hadrosaurs and the horned ceratopsians to the armored ankylosaurs and predatory tyrannosaurs. Even the mightiest land mammals—mammoths and rhinoceroslike beasts that were up to twice as heavy as the largest elephants alive today—were featherweights compared with the biggest sauropods. From an evolutionary perspective, this singularity makes sauropods an intriguing anomaly. Evolution is rampant with examples of convergence, in which the same feature evolves more than once independently in different groups of organisms. A classic example of convergence is powered flight—flapping wings evolved in birds, bats, pterosaurs and insects, but the particular bones or other structures making up the wings differ among the groups, attesting to their independent evolutionary origins. Convergence in evolution is very common even when it comes to complicated features: warm-bloodedness, eyes that can move and focus, bipedal locomotion, the loss of limbs, the use of tools, and live birth all evolved multiple times in different animal groups. Convergence is widespread in the plant kingdom as well: carnivorous plants evolved at least a dozen times, roots evolved more than once, and even arborescence—plants taking the form of trees—evolved more than once. With convergence so common in nature, sauropods' uniqueness in size is special in itself. No other land animal has approached even a third of the largest sauropods' weight. What makes sauropods stand out from the crowd, both literally and figuratively?"

Here's some dinosaurs and prehistoric stuff ^^

#Maysozoic Day 12 - Argentinosaurus

doing an art livestream rn to try and catch up yippee!! i dont draw sauropods enough lmao i have no idea what to put in the background half the time

here's the prompt list:

dinovember day 26: argentinosaurus 🍬

[cypressure]

young Argentinosaurus making a good meal for a trio of Mapusaurus. this isn’t exactly a new drawing, I started it a few weeks ago but the taxon’s appearance on the Maysozoic list motivated to me to finish coloring it. pretty happy with how it came out!

Fossil Friday: Argentinosaurus

Argentinosaurus is a titanosaur from late Cretaceous Argentina. The animal is very fragmentary with only 14 known elements of which only two are complete.

So, how do we know it's the heaviest land animal to ever walk the earth? Well, we don't actually. We need more pieces of the puzzle before we can accurately answer that question. We can, at the very least, put in a clade though.

In a paper describing the holotype of Argentinosaurus, we can see the characters it possesses that place it within titanosauria:

"Argentinosaurus huinculensis is identified basically with Titanosauria, by the presence of diverse characters whose association is characteristic of this clade, and that have in part been already been pointed out and illustrated by Powell (1986): a) opisthocoelous dorsal vertebrae with relatively small, elliptic pleurocoels, located in the middle and anterior sector of the vertebral body, in a wide pleurocoelic depression of 8 oval form, more wide in the anterior sector than in the posterior; b) presence of very clear, angular fossae, in the lateral face of the neural arch of the dorsal vertebrae; c) neural spines of the anterior dorsals rather flat, wide transversely, and without vestiges of bifurcation; d) presence of large bony cells in the entirety of the spongy tissue of the dorsal and sacral vertebrae." (https://www.naturalhistory.si.edu/sites/default/files/media/translated_publications/Bonaparte%26amp%3BCoria_93.pdf)

Argentinosaurus was found in the Huincul Formation composed of green and yellow sandstones up to 820ft (250m) thick. It is thought to represent a drainage system of a braided river.

Plants known from this formation include hornworts, liverworts,

ferns, clubmosses,

gymnosperms (including gnetophytes like ephedra and conifers)

and angiosperms.

Animals found in this formation include lungfish, gar,

turtles, squamates,

sphenodonts, crocodiles,

and many dinosaurs including titanosaur Choconsaurus, rebbachisaurids Cathartesaurus and Limaysaurus, carcharodontosaurid Mapusaurus, abelisaurids Skorpiovenator, Ilokelsia, and Tralkasaurus, noasaurid Huinculsaurus and paravian Overoraptor.

Tune in on Monday to learn all about diplodocids in more detail. Fossilize you later!

Results from todays flocking paleostream

First we had Altispinax, which I had to speed run eating to finish this little baby

Then, to the dismay of some, we did thyreosaurus which was my idea, whith some curious Spicomellus approaching. Also I would like to clarify that I am not a lazy bastard as I suffered with everyone

Then I did a newborn ornithoprion with zebra shark colors

Then we did mapusaurus and here he is cuddling with argentinosaurus as they are tired of fighting

What is this? Are the trees moving because of the wind? no….the earth also rises…perhaps the forest has come to life…It's Argentinosaurus!! the giant among giants
