March Madness: Bracket 1

It is officially time or March Madness! This year we are pitting the biggest of the big against each other (unless hey were in a previous March Madness. Sorry Argentinosaurus and Deinosuchus!). Remember, this is not about "who would win in a fight". These organisms have a lot more going for them than that.

So, without further ado here are the first two competitors: Campanile giganteum vs. Platyceramus platinus.

Campanile is the largest gastropod ever at a whopping 35 inches long. That is almost 3ft (1 m) long!

Platyceramus on the other hand is the largest bivalve ever. Typically around 3ft 3 in across, the largest one on record was over 9ft across!

Which of these shelled giants should move on the the next tier?

my fossils :)

got some shells, corals, ear bones, various scutes, bivalves and various animal teeth! i like to think about the "x" rock a lot and wonder what it is. right now i like to think it's a mark of predation of some kind.

Recently I’ve started fossil hunting, and I’ve found several things on the surface of boulders in riprap along the Chicago river. I have no idea what species any of these things may be, but I know it’s at least mostly stuff from an ancient ocean floor. This includes things like bivalves and corals—many corals. These are pictures of a handful of the things I’ve found with a ruler for scale.

@mollymerula and @wilderminds both said they’d steal my fossil rock so here’s some pictures of it. It’s a bunch of crinoid fossils that are pretty small but there’s a lot of them

[drhoz]

a few more fossil molluscs from NZ, that @purrdence found at a B&B on the Fossil Coast. Unfortunately she didn’t ask exactly where the owner had found them, so narrowing down an ID is beyond me, beyond two scallops and what might be a brachiopod.
