The wierd world of fossil worm cocoons
Curious fossils in continental sedimentary strata that range from about a millimetre in diameter up to the size of a fingernail and appear to have a net-like coating on the surface have reported for over 150 years and have been variously interpreted as the eggs of insects, parts of lichens, the food...
