The Ediacaran is the first geological period with widespread evidence of multicellular life. And those fossils are actually quite extraordinary, as many of them are of soft-bodied creatures that normally do not preserve easily in the fossil record. Most of the fossils are casts and molds in sandstones.

Review: Anomalocaris Carri (by From the Shale Plushies)
The Canadian Burgess Shale is one of the most important fossil deposits in the world due to the exceptional preservation of its fossils. Located within the Stephen Formation in British Columbia, it was deposited during the middle of the Cambrian period (or the Miaolingian, about 508 Ma).
Review: Jaekelopterus (Prehistoric World by CollectA)
The genus Jaekelopterus contains two species from the Early Devonian; fossils of J. rhenaniae were originally discovered in the Rhineland of Western Germany while those of J. howellii were originally discovered in Wyoming, USA. Jaekelopterus rhenaniae is not only the largest eurypterid, it is the largest known arthropod…EVER!

Review: Goticaris (Extinct Bath Bomb by Diamond Company)
Review and images by bmathison1972; edited by Suspsy
Goticaris longispinosa is a tiny, enigmatic arthropod originally described from both immature and adult forms from the Orsten Lagerstätten (Upper Cambrian) of present day Sweden. It was originally described as an early offshoot of the clade Pancrustacea but is now considered stem-group Mandibulata outside of Pancrustacea.

Callichimaera perlexa is an enigmatic crustacean from the Middle Cretaceous. Fossils have been found in the Churuvita Group in Colombia and the Frontier Formation in the United States. C. perlexa evolved during the Cretaceous Crab Revolution, which was a major diversification of ‘true’ crabs during the Cretaceous.
Review: Anomalocaris (CollectA)
Review and images by bmathison1972; edited by Suspsy
In 2023, CollectA added Anomalocaris canadensis to its growing collection of Paleozoic invertebrates, following fellow arthropod Redlichia and mollusks Passaloteuthis, Pleuroceras, Orthoceras, Cooperoceras, and Pravitoceras (not to mention an extant nautilus and horseshoe crab).
Review: Cooperoceras (Prehistoric World by CollectA)
Over the last 3 years CollectA has produced FIVE extinct cephalopods spanning the geologic ages between the Ordovician and the Cretaceous. A magnificent achievement that appears to have come to an end, for alas, no cephalopod has been announced for 2023. But do not despair, with figures of Koolasuchus and Anomalocaris on the horizon CollectA is continuing their streak of releasing the most diverse and interesting assortment of prehistoric critters of any mainstream company.
Review: Pravitoceras (Prehistoric World by CollectA)
Most paleontology enthusiasts are familiar with ammonites, the predatory mollusks with muscular arms and calcium carbonate shells. Most ammonites’ shells were disc-shaped coils (planispiral) that contained chambers, some of which afforded buoyancy, and one of which housed the squishy parts of the animal.
