Recommended Posts

AcadianofNS

Found on Cape Jack Beach Nova Scotia. I have 3 more like this. Stigmaria Root?

 

I have one I know is an imprint.. but is this one a fossilized piece of root or an imprint? 

 

Would love any insight! Thanks in advance. 

 

I have more pictures but they are 3mb each.. Can I post more?

I will post a few more photos of it.. 

 

1. Would you say it is an imprint, or a fossilized piece? 

 

2. Also what would you date this too? I've been reading ~300mya   

 

I'm in a unique part of the world I'm hoping to find pieces that would be dated to "Romer's Gap"

I think it is a print as I see no structure in the rock under the surface.

In the absence of internal structure, you might be dealing with a cast (see image). Yet, the structure appears quite two-dimensional to me, suggesting the specimen at least is flattened to some extent...

Below another example of a three-dthree-dimensional cast, here of Sigillaria.

Thanks for the information guys ... This is my first time on the forum... I'm super impressed with the quick responses. 

 

That being said I have a few more pieces I will take pictures of to get your opinions.

 

Paleoflor: I was unaware of "3d casts" ... this does seem to match. Thank you
