Finished preparing this big old crab a couple of weeks ago. Easily the most difficult prep that I've attempted because of spotty preservation and pyritization. Estimating that I spent about 240+ hours on prep and it is still ugly. Have not been able to ID yet, but hopefully there is enough detail to come up with an ID eventually. What do you think, Alex? Was enclosed in a nodule that was broken. Collected the larger piece in February 2019 and the right cheliped in September 2018. The carapace is about 8.5" long and 8.0" wide. The chelipeds, measured along the outside edge are about 22" long and are about equal in size. Attached are a few photos. Collected from the lower Ripley Fm., Upper Cretaceous (Late Campanian) in south-central Alabama, USA.
