In the first of two episodes on notorious fossil fails, Rob and Susie take a look at how a serious case of mistaken identify unfolded for some Ediacaran 'fossils'. Herein lies a cautionary tail for all relating to pareidolia: our very human tendency to perceive patterns in random shapes and lines, or why we might see jesus is a piece of toast or a smiley face in a cut pepper. This takes us to unexpected destination for hunting for dinosaur fossils: the moon!

Image 2: "Fossilised embryo of a dinosaur inside the egg on the moon". Yes you read that right.

The final paper is by Hari Mohan Saxena and Jagmohan Saxena "Dinosaur eggs with fossilized embryos on the moon" 'published' in the New York Science Journal (http://www.dx.doi.org/10.7537/marsnys160823.030).
