ID help, please! Lake Huron

Recommended Posts

Hello - new here! My 5 year old son has taken an interest in “rock collecting”. We have a cabin on Drummond Island, Michigan - part of the Upper Peninsula of Michigan. We found this in the shallow water of a rock beach of Lake Huron. 

 

They look like bones in here to me, but I honestly haven’t a clue! I’m a history teacher, but one geology class in college hasn’t helped me much with this new adventure. :) 

 

I appreciate any thoughts! Thank you!

It looks like your son has found some nice bryozoans.  I'll leave it to the "moss animal" experts familiar with the area and age of exposure to better ID the genus and species.

look like worn bryozoans to me also

+1 for Bryozoans.

They are invertebrate burrows

I don't know if a burrow would fork twice like the second photo. My thinking is that this is a bryozoan.

 

 

Mark.

 

Fossil hunting is easy -- they don't run away when you shoot at them!

Although this is likely bryozoan, worm burrows can appear “forked” through multiple entries, such as Phycodes ottawense.

Bryozoans, I agree. Blown up and sharpened a bit:

I agree with the bryozoan assessment. Especially with the closer view of the surface structure.
