Dinosaur eggs came in many sizes. The smallest known dinosaur— crow-sized Microraptor (MY-kroh-RAP-tur)—probably had small eggs. As for big dinosaurs, scientists say eggs couldn’t be much bigger than a soccer ball.

Answer (1 of 3): Many were bigger… but as much bigger as you might expect. See, eggs have a mechanical limit to their size. The embryo inside an egg needs oxygen, so the shell cannot get too thick. This means that if an egg gets too big, the shell will be too thin to support its weight and ...

This is a partial clutch made up of five observable eggs, with the longest 45 cm (18 inches) in length, and around 15 cm (6 inches) across, and the body of a baby theropod dinosaur on top.

Some dinosaurs were absolutely huge, so it makes sense that their eggs could be too. The biggest could be 60cm in length - that’s four times the size of an ostrich egg!

The first fossilized dinosaur eggs found (and the biggest yet to be found) were football-shaped Hypselosaurus eggs found in France in 1869. These eggs were 1 foot (30 cm) long, 10 inches (25 cm) wide, had a volume of about half a gallon (2 liters), ...

Every effort has been made to ensure accuracy, but it is always important to do your own research. This guide is merely a snapshot of information taken from...

Bigger eggs need thicker shells for support, but · Mark Norell, Macaulay Curator and chair in the Division of Paleontology, discusses dinosaur reproduction in the video above.

But surprisingly, the babies that hatched out of sauropod eggs were generally no bigger than a modern adult goose. Sauropods didn't start out extremely big—they just grew very, very fast.

July 19, 2018 - The team say their work explains why the giants of the dinosaur world ended up producing eggs no larger than an ostrich egg. Despite the vast size of sauropods (estimated to measure up to 33 metres and weigh up to 16 tonnes), their eggs only ...

A fossilized dinosaur egg measuring just 29 millimeters in length, discovered in Ganzhou, East China’s Jiangxi Province, has been identified as the smallest complete egg fossil known to date and belonging to a new species within the family ...

October 22, 2024 - The smallest egg is 1.1 inches (2.9 centimeters) long, smashing the previous record for the smallest nonavian dinosaur egg, which was held by an egg recovered from Japan. That one was laid by the chicken-size dinosaur Himeoolithus murakamii ...

5 hours ago - Two dinosaur eggs, each about five inches (13 centimeters) across and almost perfectly round, have surprised scientists in eastern China.

May 22, 2024 - The accurate identification of dinosaur egg accumulations as nests or clutches is crucial for understanding the reproductive behaviour of these extinct species. However, existing methods often rely on the presence of complete eggs and embryo remains, and sedimentological criteria that are only applicable to well-structured sediments.

September 3, 2025 - They are at least 34 centimetres (13 in) long, but the largest specimens are over 60 centimetres (24 in) long. They are also very elongated, usually roughly three times longer than they are wide.
