Here's a cracking fossil: a receptaculites? molding a gastropod shell. Collected by me from the Ordovician period in Quebec, Lorraine Group part of the Nicolet River Formation. Although this photo is not visually spectacular, it is still of great paleontological interest. If the receptaculites is oval instead of being circular, it might be because the gastropod had started to eat the rim in a spiral motion, and then a fatal event sealed they destiny?. The duo were suddenly buried to the delight of us paleontologists who can now study the interaction of two distinct species. We can see clearly the trace of the gastropod shell in the softer receptaculites, the shell which left the imprint has since come off. I believe the two species to be respectively R. Occidentalis and Murchisoniidae or may be an Hormotoma gracillis like the one in @Jeffrey Pcollection . I'm probably wrong, it could also be a colony of bryozarians instead of receptaculitids, I'm not sure. Because of the bad condition of the fossil, I'm unable to see the sunflower pattern. What do you think?

Ordovician fossils from the Nicolet River Formation, Laprairie, Quebec
Jeffrey P posted a topic in Fossil ID
Found these on Tuesday at the Hansen Brick Quarry in Laprairie which is just minutes from downtown Montreal. In addition, found a number of bivalves, gastropods, crinoid pieces, brachiopods, and a few partial and one complete Flexicalymene trilobite. Thought this might be a piece of nautiloid shell, but have never seen ornamentation like this. Not sure what this is. Thought it might be a bryozoan covering (something?).

Leptaena moniquensis (brachiopod) Upper Ordovician Nicolet River Formation Lorraine Group Hanson Brick quarry LaPrairie, Quebec, Canada Looks very similar to Leptaena rhombonatis which I've found in abundance in the Helderberg Group/Lower Devonian. -

These are some Ordovician trilobites I found 7/27/14 in LaPrairie, Quebec in the Nicolet River Formation. I believe some or all of them are Flexicalymene, but I'm not completely sure. A little help with the iDs would be very appreciated. Thank you.
