However, trace fossils attributable to ground-dwelling spiders are still poorly documented in the geological record.Most of these early segmented fossil spiders from the Coal Measures of Europe and North America probably belonged to the Mesothelae, or something very similar, a group of spiders with the spinnerets placed underneath the middle of the abdomen, rather than at the end as in modern spiders.

the fossil spinneret was compared most closely with posterior median spinnerets of the primitive spider suborder Mesothelae. The distinctiveness of the cuticle enabled us to associate the spinneret with remains previously referred tentatively to a trigonotarbid arachnid (2). Restudy of this material resulted in5 Geratonephila Burmanica. The fossil that contained the body of a male Geratonephila Burmanica was an important discovery in many ways. Besides giving scientists a better image of what these prehistoric spiders looked like, they confirmed the belief that spiders could have any kind of social interchange with other spiders.

Fossil spiders occur in rocks of various different types, but the vast majority and best-preserved spiders are found as inclusions in amber from various localities dating back to the Cretaceous, although preservation tends to be better in the younger (for example, Miocene and Eocene) ambers.
