I'm cleaning out a folder of images on my computer and I found these pictures of some plants from the Carboniferous of Spain.
The first specimen is of Neuropteris ovata
The second specimen is Annularia stellata
Both specimens come from near La Magdalena in the state of León, Spain. They are estimated to be from the Stephanian B stage (of the Carboniferous in Western Europe which correlates to the Kasimovian stage of the ICS and the upper Pennsylvanian period (Missourian stage) in North America. Check out this page on Paleontology Online for a handy reference chart of the regional stages of the Carboniferous.
