Fossiliferous Limestone Varves – USA

Montlivaltia sp.

£1.50 – £3.50 ex VAT

Pitchstone Slide

£18.00 ex VAT

£2.25 – £6.00 ex VAT

Specimens of Fossiliferous Limestone Varves, collected from Wyoming, USA. Varves are alternating sedimentary sequences, associated with lacustrine deposits and seasonal cycles of temperature changes. These specimens display faint varves (lighter and darker bands) down the edges of each piece. These specimens may also contain partial fish remains and are an example of Lagerstätten. This is a German term that refers to a sedimentary layer with unusual occurrences of fossils that have undergone relatively high grade preservation. These specimens are Eocene in age and part of the Green River formation. Specimens are available in multiple sizes and come in a white card tray with an information label.

Puddingstone
Puddingstone Conglomerate £1.50 – £6.00 ex VAT

Specimens of Puddingstone, collected from Hertfordshire, UK. Puddingstone is a variation of conglomerate, which is term used to describe a coarse grained sedimentary rock, featuring large, well rounded clasts in a finer grained matrix. It dates back to the Paleocene to Eocene period around 56 millions years ago. This particular rock is composed almost entirely of silica and has no porosity, likely contributing to its notorious hardness. This rare rock is only found in quantity at one locality in Hertfordshire. As such, it is becoming exceedingly difficult to obtain. This rock is available in multiple sizes and each piece comes supplied in a white card tray with information label.

The igneous pluton formed during the Permian period, 292 – 298 million years ago during the the Variscan orogeny. A beautiful rock to observe due to its coarse crystalline texture and schiller effect, the samples are ideal for general interest, collectors and educational use with specimens being available in three sizes and come supplied in a card tray with an information label.
