npub14k23hl0c7a0ecs42wndgxg4l7w9ve03jtdlg48hvj93zdtq2cf9q3ted68 (npub14k2…ed68) Concretions like this are wonderful 😊 . They preserve 3D fossils because they grow before the burial that might crush the fragile remains. I did this wee graphic for some similar ones (but which also show later "septarian" cracking). Your Whitby one grew like this, but for some reason, did not crack - maybe more complete mineralisation of bacterial slimeball? #Geology #Septarian #Diagenesis
