Pennsylvanian Road Cut Collecting in Oglesby, Illinois (11-10-19)


Recommended Posts

When I woke up this morning I look outside and saw that it was going to be a nice day in the low 40's and I decided to go out and do a little collecting before it gets really cold and the snow shuts everything down. So i figured why not do the 130 mile round trip to Oglesby, Illinois and collect a nice road cut that I have been to several times that exposes the Pennsylvanian LaSalle Limestone member of the Bond Formation. As with all of the other times that I visited, I was the only one at the site. I only spent about 1 1/2 hours here looking around. I did not collect a lot of fossils, but did pick up a few. If you like brachiopod hash plates, you can find some nice ones just sitting there waiting for someone to pick them up. You do not many weathered out fossils at this site since most of the rockfall is recent, but you can find Composita argentia laying around sometimes- these cool brachiopods pop out of that matrix when struck by a hammer or in natural falls.

 

Here are some pics of the area, hash plates and some small pieces that I collected in the field.

That is a big Juresania nebrascensis, I found another one about 1/2 the size bigger, but it was in a large boulder, so I left that and tons of other brachiopods for others to collect.

Adam, do you think the last pic in my post is of a bivalve?

Yes, looks like it to me, an unusual find, but I don't know which genus. 

Nice. :)

Wow! These finds are incredible!

Wish I had the opportunity to collect stuff like this. 

:envy:

It is a real nice little road cut and usually every winter some more of the wall fall downs exposing more stuff.

I'm glad you could get in before the cold and snow hit! Nice finds, I have been spotting more bivalves as I have spent time at this site, they are not as obvious as the brachiopods but I think there are quite a few there.
