Recommended Posts

Found this today....The area never ceases to amaze me...always something new to find.   Thanks to those below in identifying this as an arthropod trackway fossil.  Would like to try to see if it can now be narrowed down to which type of arthropod if possible ?

Really cool find!

I don't think this is a plant however, I am not really familiar with the lake skiatook fossils but this appears to be a beautiful arthropod trackway fossil.

I agree this is a beautiful arthropod trackway.

Very cool.

Oh my gosh how cool is that :)  Now I have to look up what a trackway is...footprints I assume?

I think this is Protovigularia, a bivalve locomotion trace.

Can't say I saw it, but I definitely agree.

Primary indication: depth of sediment penetration.

Thanks for all the info folks...Rockwood, great observation on the depth of sediment penetration.

 

The mystery deepens for me.  "Protovigularia is a plaited burrow consisting of obliquely arranged pads of sediment ..."

 

I was looking over a research paper*(linked below) especially at the images.    It had both arthropod trackways and bivalve locomotion traces. Couldn't find anything that really stood out to me clearly that was similar to mine.  If anyone has an image that seems similar to mine would love a link...Thanks!!!
