Retispora lepidophyta is a spore type and an important biostratigraphic marker of the latest Devonian period.[3][4][5] The last appearance of Retispora lepidophyta defines the Devonian-Mississippian boundary in Belgium and other places.
Description
[edit]Retispora is trilete, reticulate, and has a distinctly "fried egg" appearance, as the spore is zonate, and the inner area is much darker than the outer area.[2]
