Fossil Ids Needed From Harrogate, Tn


Zapins

Recommended Posts

I found these near the medical school I'll be going to in a month for the next 4 years :) So I'll have plenty of time (or maybe not due to the studying) to search the outcrop I found these at.

What is this? A leaf? A squashed lizard or fish spine?

I assume this is one of those helicopter tree seeds?

Some kind of leaf?

No idea what this is.

1 - looks like a Calamites sp. node.

2 - looks like a partial, indeterminate leaf.

3 - looks like a Neuropteris sp. leaf.

4 - looks like a Calamites stem section.

It would appear that it is a carboniferous era outcrop.

Regards,

EDIT: According to this geological map, at least part of Claiborne County has Pennsylvanian aged sediments - the other part is Ordovician aged.

Thanks.

Do you think there is a possibility that I could find non-plant specimens at this location? Perhaps insects or small vertebrates? Or is that not very likely?

Possible, but Carboniferous insect fossils are rare, and vertebrates vanishingly so.

Interesting. Why are insects rare? Weren't they extremely common in that era?

Not as common as plants, but yes, they were numerous. The difference in occurrence in the fossil record is no doubt a matter of preservation; the bacteria that 'ate' insects had been around for quite a while, but plants had more recently added lignin to their make up, and neither insects nor bacteria were good (yet) at breaking it down. This is one of the reasons that we have such massive deposits of coal from that era.

Insect fossils are really a product of very rapid burial in an oxygen-deprived low-energy environment, which really only occurs in special circumstances.

they were common but dont preserve well, Most Pennsylvanian sediments dont lend themselves to preserving insects. It takes very fine grained sediments (Florrisant ash or resins for example) to preserve insects.

Hmm a pity. It would have been interesting to find some. Apparently insects aren't found in early carboniferous layers, usually only the later layers.

Some sites are better than others: LINK

I would still keep my eyes open, you might find such a site!
