Recommended Posts

Hello everyone,

All of these were found in St. Claire, PA. Llewellyn Formation. Any idea what they are?

 

#1. Plant leaf of some sort?

#2. Scaley looking fossil?

#3. Some sort of fern stem?

#4. Calamites segment? Pattern continues all around it.

So #3 is like a fern tree root, interesting!

Thank you for the IDs.

#1 Difficult to ID from photo, longitudinal striations may indicate some calamite stem or cordaite leaf fragment, but there are more options possible here.

#2 could these be coal cleats, i.e. represent a lithological rather than biological feature?

#3 As Abyssunder said, Stigmaria, with were the "root-like" organs of lycophytes (Lepidodendron, Sigillaria, etc.), rather than of tree ferns

#4 As Abyssunder said,Calamites

#5 Could you annotate the photograph? What do you mean with segmented? Term suggests calamite, but I have difficulty seeing past the mineral staining on this photo.

#6 Stems, possibly a calamite, need to look for nodes to confirm. Alternatively, possibly some type of pteridosperm stems?
