Promicroceras multi-bed in limestone from the Lower Lias of Charmouth, Dorset, UK.
Matrix: Moderate limestone, well consolidated. Approx. 80 x 65mm
Difficulty: ★ ★ Moderate. Relatively easy to clean. Engraver or an air pen (air scribe).
Mostly popped, but all proms need tidying up at least. Further ammonite on the back that requires full prep. All appear to be horizontal which makes it easier. Could be a little sticky in places.
