A fine example of a great British classic dactylioceras commune ammonite, two specimens reside within the one split stone nodule, once part of the silty seabed where the extant cephalopods umbilicus (shells) would reside post their demise, to be covered over and eventually harden into the fossil time capsules from a prehistoric Jurassic period of England. The superb duo coupling have been exquisitely and perfectly cleaned and prepped out of the limestone shales, so each defining point of both are fully exposed, seemingly as though one may have just lifted the ancient shells from a sandy beach.
The larger umbilicus has an excellent mouth border still intact, this is a rarity. The mouth aperture flares out at this point creating a trumpet bowl effect, which is very attractive. Coupled with a second specimen micro conch this is a particularly attractive novice and aficionado collection piece. The smaller umbilicus has the iridescence of iron pyrite, fools gold, this contrast with the darker chocolate brown of the larger ribbed shell, which is good enough to eat from a collector point of view!
