CodeBlueBlog puts to rest whether the fetal foot impression was real
“Well, ladies and gents, if you’ve ever seen an X-ray of a newborn foot you would notice that there is very little mineralized bone present. This image shows impressions created by distal phalangeal tips that don’t exist in the fetus; the lateral ridge in this image would represent an abnormally flattened calcaneus, if a fetus had a developed calcaneus — which it doesn’t; finally, what are those two bumps — lateral and medial at the base of the phalanges? If someone is trying to simulate the os of the great toe on one side — puleaze…those won’t be calcified for years. The bump on the medial side? I dunno. This might be an alien.
One last addition…the asymmetric impression of the phalanges implies an amount of dorsifelexion that this foot is not capable of.”
