Collector Promicroceras marstonense ammonites from Somerset Rare Promicroceras marstonense (Spath 1925) from the Lower Lias (Sinemurian), Marston Magna limestone, Obtusum Zone, Somerset. These nodules contain a rich ammonite deathbed assemblage. They are highly sought after by collectors around the world. A very limited amount was excavated from the site, hence the rarity. They are very similar to the Promicroceras planicosta that are found in Lyme Regis, and make a great companion fossil. We are offering these specimens for an affordable price. We hope to get a few specimens here and there on our travels in the future.

Somerset Oolite Jurassic Ammonites These classic ammonites are found around the fields in Ilminster, Somerset. They are virtually the same species as those found in in the Whitby Upper Lias. Their cream colour makes a nice contrast against the darker tones of those found up in the north of the country.
In Somerset, they are discovered by ploughing the fields of the area, sometimes the soil only being a few inches thick, on top of bedrock. Loose bedrock is lifting up during the process, as is the natural heaving process of uplift, from frozen water in the rocks, cracking and pushing them upwards. Surface weathering and rain cleans off much of them. Beacon Limestone Formation (‘Junction Bed’ Oolite of Ilminster, Somerset, UK. 160 Million years old. Jurassic age. Field walking (with permission of course) is the best way to find them.
Dactylioceras Ammonites Normally Dactylioceras commune & tenuicostatum (plus many species are described from this location)
Polished Somerset Oolite Jurassic Ammonites These classic ammonites are found around the fields in Ilminster, Somerset and with a little help from human hands, they are cut and polished, shaped and smoothed down to a perfect shine. These really do compliment an ammonite collection, and they also show what the inside of the ammonites look like now after all this time.
