Infant Diplodocus hatched out of eggs roughly the size of a large grapefruit, and if they were lucky, the dinosaurs grew to be more than 80 feet long as adults. And the little sauropods were not just small copies of adults.Infant Diplodocus hatched out of eggs roughly the size of a large grapefruit, and if they were lucky, the dinosaurs grew to be more than 80 feet long as adults.

What size were dinosaur eggs?
These eggs are more than 60 cm (2 ft.) long and about 20 cm (8 in.) in diameter. Until recently, whenever a dinosaur fossil was found in association with fossilized dinosaur eggs, palaeontologists thought the dinosaur had been stealing the eggs at the moment disaster (such as a sand storm) buried them.
What is the largest dinosaur egg ever found?
The object was more than 11 by 7 inches in size and looked like a deflated football. Clarke immediately realized that The Thing was a giant egg — a soft-shelled egg. And it was from 66 million years ago, around the time when an asteroid hit Earth and led to dinosaur extinction.
Did Diplodocus lay eggs?
The documentary Walking with Dinosaurs portrayed a mother Diplodocus using an ovipositor to lay eggs, but it was pure speculation on the part of the documentary author. For Diplodocus and other sauropods, the size of clutches and individual eggs were surprisingly small for such large animals.
How big is a Tyrannosaurus rex egg?
about 17 inches long No one has yet positively identified tyrannosaur eggs or hatchlings, but the size of the new embryonic dinosaurs matches with large, elongated eggs that paleontologists have found before. From the size of the embryos, researchers think tyrannosaurs were curled up in eggs that measure about 17 inches long.
How big is a brachiosaurus baby?
Their findings suggest the creatures, which lived more than 70 million years ago, were around around 1 metre (3ft) long when they hatched, despite being able to grow to over 12m (40ft) long and weigh around 8000kg.
How big is a brontosaurus egg?
How big is a brontosaurus egg? The eggs were about 1.5 inches (4 centimeters) long and just over 1 inch (2.5 centimeters) wide, which is a little smaller than a chicken egg. But even large dinosaurs had small babies.
Is there any dinosaur eggs left?
Granger finally said, 'No dinosaur eggs have ever been found, but the reptile probably did lay eggs. These must be dinosaur eggs. They can't be anything else.
Do we have dinosaur DNA?
Oct 26, 2021. A team has extracted what could be DNA molecules from a 125-million-year-old fossil dinosaur, according to a study published last month (September 24) in Communications Biology. But other experts have voiced caution or outright skepticism about the findings.
How long did a Diplodocus live for?
Early estimates of 300-year lifespans for the largest sauropods were based on comparisons with crocodiles and turtles, which have much slower metabolisms. The consensus is now that Apatosaurus and Diplodocus dinosaurs probably only lived for 70 or 80 years, which is about the same as an elephant today.
