Sauropod Dinosaur Egg by Dinosaur Corporation

Sauropods' most notable trait was their immense size, even the smallest ones, like the dwarf sauropods, were among the largest creatures in their habitats. Their only size rivals were the rorqual whales, but unlike them, sauropods lived exclusively on land. Some, such as diplodocids, held their heads low, while others, like Camarasaurus, kept them high. Despite their size, sauropods exhibited considerable diversity. Some, like diplodocids, were exceptionally long with incredibly long tails that could potentially crack like a whip to produce sonic booms. Supersaurus, at 40 meters (130 feet), is likely the longest, but Seismosaurus and even the previous record holder, Diplodocus, were still remarkably long. Amphicoelias fragillimus, known only from a single vertebra drawing, would have had a spine longer than the blue whale. The longest land animal today, the reticulated python, only reaches 10 meters (33 feet). Others, like brachiosaurids, were extraordinarily tall with high shoulders and extremely long necks. Sauroposeidon is probably the tallest, reaching about 18 meters (60 feet) high, surpassing the giraffe's height of 4.8 to 5.5 meters (16 to 18 feet). Some were astonishingly heavy: Argentinosaurus is likely the heaviest at 80 to 100 metric tonnes (90 to 110 tons), with Paralititan, Andesaurus, Antarctosaurus, and Argyrosaurus being comparably massive. There's uncertain evidence of an even more colossal titanosaurian, Bruhathkayosaurus, which might have weighed between 175 to 220 tonnes (190 to 240 tons). The largest land animal today, the Savannah elephant, weighs no more than 10 tonnes (11 tons). Among the smallest sauropods were primitive Anchisaurus (2.4 meters, or 7 feet) and Ohmdenosaurus (4 meters, or 13 feet), dwarf titanosaur Magyarosaurus (5.3 meters or 17 feet), and dwarf brachiosaurid Europasaurus, which was 6.2 meters long as an adult. Its small size was likely due to insular dwarfism of a stranded herd on an island now in Germany. Notably, the diplodocoid sauropod Brachytrachelopan had an unusually short neck, unlike other sauropods whose necks could grow up to four times the length of their backs.
