What scientists are calling the “world’s oldest meal ever discovered” was recently unearthed in Russia. The fossil was of a slug species, called Kimberella, is estimated to be around 550 million years old. Remains of its “last meal” were uncovered when the residue of ancient types of plankton and bacteria surfaced in scans of the fossil.

Finding marine fossils isn’t exactly a rarity — many ammonite shells and smaller primitive fish bones have been found everywhere in the world, from the plains of Antarctica to the Saharan Desert. However, finding fossils preserving other features, such as meals, phenotypical features (such as feathers and skin), and even preserved skulls, are difficult due to the long periods of changing climate and age. Only recently have paleontologists been able to make assumptions with physical proof about ancient organisms’ diets and more.

A discovery that I found particularly beautiful is the preserved skeletons of a velociraptor and protoceratops. It’s cast is currently displayed in Nagoya City Science Museum in Japan. This was one I recently found out about, and highly recommend checking it out!
