Was going through a box of material from Holmdel, Monmouth County, New Jersey (Upper Cretaceous) and came across these two pieces that I can't identify. My best guess is that they are both concretions, but I wanted to ask the hive mind before I discard them. In full disclosure, I am offloading all of my Cretaceous material so if either of these is something significant, I will either be selling or donating them.
Thanks
Dave
