That being said…bone fragments the size of humans combined with finding it in Argentina does suggest this is gonna be a big motherfucker, world’s largest or not. The list for probable longest and heaviest sauropodomorphs (bigass long-necked fuckers) is basically an assortment from the western US, Argentina and one or two from China.
Scientists have unearthed a massive, 98-million-year-old fossils in southwest Argentina. Human-sized pieces of fossilized bone belonging to the giant sauropod appear to be 10-20 percent larger than those attributed to the biggest dinosaur ever identified
“Biggest dinosaur ever identified” is a topic of…continued and intense debate. Sauropods tend to leave pretty fragmentary fossils, and reconstructing a whole animal from loose bits is tricky. Maraapunisaurus (Amphicoelias) is a particularly notorious one as the original specimens for it are lost (probably disintegrated, they were found before preserving fossils was invented) and estimates range from 200ft and 170 tons to ~100 feet and 70 tons.
This is not really related to your comment, but you seem to know a thing or two about dinos so maybe you’re the right person to ask. AFAIK it takes a lot of hard work from the Earth and time to make fossils, so given that, surely there must be shit loads of dinos as well as entire species of dinos that didn’t get turned into fossils, right? Are there any estimates on how many species of dinos there could have been that we may never know about or is that just impossible to guess? Sorry if this is a stupid question.
Shout out for my boy Barosaurus—lived in what is now North America during the Jurassic period. From a book resulting from a survey of sauropod sizes, in 2020 Molina-Perez and Larramendi estimated it to be 45 meters (148 ft) and 60 tonnes (66 short tons)—the longest animal that’s ever been. The book is “Dinosaur Facts and Figures: The Sauropods and Other Sauropodomorphs”. Note that this weight still likely places it behind the biggest titanosaurs (such as the one in the subject article) in terms of mass. But that is a long animal.
— thank you for shining. Very intriguing and interesting!
bone belonging to the giant sauropod appear to be 10-20 percent larger than those attributed to Patagotitan mayorum, the biggest dinosaur ever identified
Not really true . Many bones found from Patagonia, where many of the super massive sauropods have been found, have fairly intact fibula and humerus bones. The most massive, Dreadnoughtus has a partial skeleton, but a substantial amount of bones that are intact like the fibula and humerus that have been very useful in determining a confident estimate of mass. You dont neeed really all the bones to estimate the mass of the sauropods, you really need a few vertebrae and the leg bones, which due to their mass and density, are highly likely to survive the test of time.
I don’t think I’ve ever heard of Patagotitan as biggest. Wikipedia puts it in a close 8th by length, and a distant 9th by weight.
