2 Cone: Equicalastrobus chinleana, Eocene, Morocco

The strobilus (cone) of a horsetail shown here impressively demonstrates the reproductive structure of this primitive plant group. The cone has been cut lengthwise and polished so that the sporangia are visible – small capsules that open lengthwise and release spores. When these spores encounter suitable environmental conditions, they germinate and form a new horsetail plant.The cone structure is clearly visible on the reverse side.Time: Upper Eocene, Priabonian,Location: Dakhla, Sahara, MoroccoCone size: 2 x 5,5 x 0,7 cm each Size of floating frame: 7 x 7 x 2 cmThe cone is delivered in the floating frame and with a detailed label, as shown.

In the Tertiary period, water levels in the Rhineland were so high that the Lower Rhine Bay was a sea. The mangrove forests and coastal swamps of this period caused so much plant debris to accumulate that large coal seams were formed. These cones are sometimes found among them.Age: Neogene, Miocene, Horizont 7;Locality: Opencast Hambach, North Rhine-Westphalia, GermanySize: 9,5 x 3 cmColors on product photos may differ slightly from those of the original specimen due to technical reasons.

Sequoia abietina, also referred to as a fossil species of the genus Sequoia, is an extinct conifer that was present during the Oligocene to Miocene. It is closely related to modern redwoods (Sequoia sempervirens) and was part of ancient subtropical and warm-temperate ecosystems.Such remains have been discovered in various locations across Europe, including Germany and Austria, often in lignite deposits or sedimentary formations of the late Oligocene to early Miocene.Age: Upper MioceneLocality: Inden open-cast mine, Rhineland, North Rhine-Westphalia, GermanySize: approx. 1,5 cmThe pictures are for reference, with your purchase you will receive one specimen of comparable quality.Colors on product photos may differ slightly from those of the original specimen for technical reasons.
