156 SAUROPODOMORPHAPATAGOTITAN MAYORUMLATE CRETACEOUSCERRO BARCINO FORMATIONSOUTHERN SOUTH AMERICAWHAT WERE THE BIGGEST DINOSAURS? THIS IS A DIFFICULT QUESTION BECAUSE THERE ARE A NUMBER OF CONTENDERS. MANY AROUND THE PLANET ALL COMPARE IN TERMS OF SIZE BUT SEVERAL ISSUES CONFOUND THE CHOICE OF A CHAMPION; IS BIGGEST THE TALLEST, THE HEAVIEST OR THE LONGEST? THE QUESTION IS LIKELY TO GENERATE THREE DIFFERENT ANSWERS. ALL THINGS BEING EQUAL, PATAGOTITAN MAYORUM IS ONE OF THE LARGEST, IF NOT THE LARGEST, EVER COLLECTED.In 2008, a worker at an estância in southern Argentine Patagonia, came across some bones weathering out of a small hill in a very arid valley. He reported these to the owner, who then alerted paleontologists at the regional museum in Trelew, the capital of Chubut province. The abundance of fantastic fossils in this area has made it a hotbed of paleontological discovery for over 100 years. This has fostered a very talented group of paleontologists at the Egidio Feruglio Paleontology Museum in Trelew. When they first saw some of the specimens, they were immediately enthusiastic: this was a very large animal and competitor for the largest land animal to exist.Excavations in the approximately 100-million-year-old sediments soon began. As a lot of soil had to be removed, and due to the immensity of the bones, progress took place over several excavation seasons. More than 150 bones of six different individuals were collected, and what they found was one of the most dramatic animals to be exhumed anywhere on the planet.Analysis of Patagotitan has demonstrated that it measured about 40m (131ft) in length, and was 5.5m (18ft) high, although others have revised the length slightly downwards. The skeleton was so large that a single femur (upper leg bone) measured over 2m (6½ft) in length. The fossilized specimen weighed over 400kg (882lb). Alive, Patagotitan has been estimated by some to have weighed around 69 tonnes as an adult; its neck is estimated at over 12m (39⅓ft) in length – and the type specimen is only about 85 per cent grown. When alive, Patagotitanroamed a forested area that was bisected by Patagotitan on display at the Field Museum in Chicago.
