F043 An attractive limestone dragonfly plaque in a solid cherry wood frame (Germany)

Jurassic (208-146 million years old)

Dragonflies belong to the Odonata, which is a sub-group of insects, which in turn is a group of uniramian arthropods. The Odonata are known to be ancient insects. The oldest recognizable fossils of the group belong to the Protodonata, an ancestral group that is now extinct. Dragonflies are generalists, they eat whatever suitable prey is abundant. The six legs are all located near the head and are seldom used for walking, but are more useful in catching prey and perching on vegetation to rest or lay eggs.

F044 A fine pair of agatised fossil corals (USA)

(23-5 million years old)

Florida agatised coral is famous for its beauty and uniqueness. It is found all over Florida in many forms and colours. Sometimes it is solid but those from Tampa Bay are hollow and can be called geodes. Scientifically it is identified as a chalcedony pseudomorph after coral because one mineral, the coral, has been replaced by another quartz.

Weight: 1.9KG Width: 16cm

F045 A fine pair of agatised fossil corals (USA)

(23-5 million years old)

The best specimens will show beautiful chalcedony replacement and sometimes quartz crystals. Fossil corals were simple marine invertebrates that possessed a sac-like body called a polyp with a mouth and tentacles. Under unique geological conditions, prehistoric corals and molluscs can fossilize by being replaced with agate from silica-rich ground water percolating through limestone. Occasionally seen as a single half, it is unusual to find a book-matched pair in such an excellent state of preservation.

Weight: 3KG Height: 23cm
