Dinosaur Embryo

The qualifications for a fossil egg can be simplified down to three characteristics: the thickness should be even, they are often rounded, and the surface should be covered in tiny pores. More often than not, there is no embryo preserved inside a dinosaur egg. This makes classification difficult as it is almost impossible to
determine the parent. This egg is a rare exception, as the minuscule bones of an embryonic dinosaur can be seen inside the egg.
