Recommended Posts

Below are items from Essex trips that have yet to be ID'ed....

Any thoughts appreciated.

1) Looks wormlike - but not sure

2) Paucijaculum perhaps but I doubt it....might be a trace fossil

3) Looks like Lepidocystis (but not sure)

Specimen 4: I miss the venation which I expect in Cyclopteris. Possibly a fragment of a striated (seed) fern stem. The striations are not regular enough to suggest Calamites or a Cordaites leaf.
