Spore type and an important biostratigraphic marker of the latest Devonian period
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.
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.
