Diplodocus had two species D. carnegii D. hallorum with the main difference being size with the former being 24-26 meters long and 13 metric tons while the ladder was 29-33 meters and 23-38 metric tons. Diplodocus swallowed gastroliths to aid in chewing since Diplodocus didn't chew rather its 35 peg shaped teeth striped the leaves then immediately swallowed this quickly damaged teeth causing them to become being worn down and replaced within a month and Diplodocus having around 5 replacement teeth in it's skull at a time. Diplodocus had a 8 meter neck with 15 neck vertabrae it's prosauropod ancestors only had 10, this is because Diplodocus converted some of it's thoracic (back) vertebrae into neck ones having fewer thoracic vertabrae than reptiles. Diplodocus had low neck posture holding its neck slighly bellow its hips its head angled downwards. As Diplodocus ate from low growth plants to avoid competition from sauropods like Camarasaurus amd Brachiosaurus who held their necks upwards to eat from treetops. Diplodocus tail had around 80 vertabrae took up half of the animals length and was used as a defensive weapon Diplodocus eggs only took around 2-3 months to hatch took around 10 years to reach sexual maturity indicating it had a high metabolism as a juvenile and a high infant mortality rate as they grew as quickly as they could. It's main predators were Allosaurus, Ceratosaurus, Torvosaurus of which likely could not take donw a full grown Diplodocus alone.
