Question

Why are fungi fossils so rare?

Answer 1

Fungi fossils are rare because they deteriorate faster and easier which makes them harder to preserve. And those that get preserved are often too small to be easily identified.

Answer 2

The reason as to why fungi fossils seem so rare is that they are usually microscopic and often difficult or impossible to identify. Not much information on fungi fossils has been documented. This could be because fungi fruiting bodies consist of soft, fleshy and easily degradable tissues which due to their poor integrity do not keep or preserve as well as animal tissue. Even when available, it takes a trained eye to recognize fungal fossils. Not many people have the training and expertise to recognize the fossils.
