Fossils from Romania - help needed :)

[Kasia]

Dear TFF Members,

 

these are the fossils I found in Humor, Romania - this is a village situated in Bukovina. They come from a slope at one of the banks of Humor river - from the point indicated on the map. I have no idea which geological era the rocks come from (I just saw a nice place with multiple rocks and I started looking for fossils), so it's hard for me to determine what I have actually found

 

The first one looks a little bit like Calamites?

The second one - like burrows?

This is what it looks like on the bottom

And there are a few little pieces with something that looks like plants

Some more of these - plant-like fossils.

 

Any ideas, anyone?

Can’t help ID, but neat finds!

Top one looks like Cordaites, the second Cruziana, trilobite trackway. That would probably make it Lower Carboniferous. The others I see a mixture of plant debris and worm burrows. The last one looks interesting, it might have something else there as well

Thanks a lot  I also thought that the second one could be the trackway of a trilobite, but as I found no other trace of them in the rocks (and I spent there quite a time :), I was not sure anymore. I'm glad my original idea was right.

 

So do you think that the plant debris in the small pieces also come from Cordaites?

 

What else could there be in the last piece?

Hi Kasia!
As far as I know, the sediments of the Humor and adjacent valleys (Moldova, Moldovita, Sucevita) are not older than Paleogene.
Almost all of the above pictures show trace fossils, in my opinion, exept the first one which may be a tree trunk or branch.
The strange shapes visible on the surface (in the last four pictures) bear a close resemblance to Chondrites igen.

Chondrites and Helminthoidea isp were mentioned from that region.

 

Nice finds, BTW !

I confirm Chondrytes
no Cruziana

Just a guess, but it's just that and I could be wrong: crossed my mind the possibility of echinoid trace fossil for the second specimen in question.

I liked the idea of Cruziana, but that would be also cool  thanks a lot!
