酷東西

趣味知識

Eolambia is known from hundreds of bones, including both adults and babies, so scientists have a good picture of its skeleton.1

The first Eolambia fossil was found by Carole and Ramal Jones in 1993, and the species name honors Carole.1

Young Eolambia were hunted by big crocodile-like reptiles that lived in the lakes, but adults were too big for them.1

Grown-up Eolambia, at least eight or nine years old, were hunted by large meat-eating dinosaurs like Siats.1

Eolambia lived in a floodplain with lakes that changed water levels over about 21,000-year cycles.1

The name Eolambia was suggested by paleoartist Michael Skrepnick, replacing an earlier informal name.1

你們都在問

關於 Eolambia 最常被問的問題

?How big was Eolambia?

About 6 metres (20 feet) long. That is about as long as a large van.1

?What does the name Eolambia mean?

It means 'dawn lambeosaurine', because scientists first thought it was an early member of the lambeosaurine group.1

?Was Eolambia a hadrosaur?

No, it is a hadrosauroid, an early cousin of the true duck-billed dinosaurs (hadrosaurs).1

?How old could Eolambia get?

Scientists estimate it lived at least 8 to 9 years, based on a subadult specimen.4

迷思破解王

迷思： Eolambia was a duck-billed dinosaur like later hadrosaurs.

真相： Eolambia was an early relative of hadrosaurs, but it was not a true hadrosaurid. Scientists place it outside the hadrosaurid family.2

仍有爭議: Scientists debate exactly where Eolambia sits on the family tree, with some originally thinking it was a lambeosaurine hadrosaurid, but later studies place it as a more basal hadrosauroid.2
