The Journal of Geology, 1937
The Geneva dolomitic limestone of the northern portion of the southern Indiana Middle Devonian region, which formerly has been considered as either a lithologic facies of the Jeffersonville or Sellersburg limestones or both or a distinct formation older than the Jeffersonville, is shown by paleontologic and stratigraphic evidence to be a lithologic ...

Sieve Cells in Phloem of a Middle Devonian Progymnosperm

Science, 1984
Phloem tissue from a Middle Devonian member of the Aneurophytales (Progymnospermopsida) is described. This may be the oldest firm evidence of conducting elements of the phloem, extending our knowledge of this tissue back some 35 million years. The discovery indicates a close phylogenetic relation between progymnosperms and gymnosperms and provides a ...
