Well the kido and I have been hunting around the reef for a while (we gave up for a bit and went to some upper cretaceous shale on a river for the summer...more opportunity to swim if she got bored lol) but today we went down to the beach to hunt for some shells for a craft and I couldn't help but look a little lol found a small ammonite (I think) and then we saw this concretion laying there I smaked it open and 432nd time is the charm haha!! It looks to be in pretty great shape even the spines are sharp on the carapace! Kinda neat that these are found only at this reef Emma (my daughter) was so excited normally I just get the thumbs up "cool dad" when we find something hahaha.
