The mystery of the 68 million year old 'giant' egg, experts are confused because...

In 2018, paleontologist Julia Clarke, a member of the research team, from the University of Texas, USA, visited her colleague David Rubilar-Rogers at the National Museum of Natural History in Chile. Here, Mr. David showed Ms. Julia a mysterious fossil. It was a "giant" egg that Mr. David discovered in Antarctica many years ago. Photo: Legendre et al. (2020).

David and his colleagues dubbed the rather large egg “The Thing.” They wanted to determine what species the soccer-ball-sized egg belonged to. Photo: Francisco Hueichaleo, 2020.

“It looks most like a lizard or snake egg . But it’s an egg from a really big relative of these animals,” said another member of the research team, Lucas Legendre of the University of Texas, USA. Photo: Francisco Hueichaleo, 2020.

According to research by experts, the super sea monster that laid the egg above could have an estimated body length of 7m from head to tail. This reptile was named Antarcticoolithus bradyi by scientists . Photo: Legendre et al. (2020).

Based on data and analysis of 259 modern reptile species and their eggs, an ancient mammal called a mosasaur (a large extinct marine lizard) appears to match the description of the egg's "owner". Photo: Legendre et al. (2020).

Legendre said the egg found in Antarctica likely belonged to a giant marine reptile. Not only was it huge, scientists were also surprised that the species laid eggs. Most reptiles of such large size do not usually lay eggs. Photo: Francisco Hueichaleo, 2020.

Paleontologist Clarke said the egg had a nearly complete soft shell. It is one of the largest fossil animal eggs ever found on Earth. Photo: Francisco Hueichaleo, 2020.
