The Cambrian was the very first period of the Paleozoic Era, beginning a little over 538 million years ago and lasting until the start of the Ordovician period 486 million years ago. And during those nearly 52 million years, all manner of weird and wonderful life evolved in the seas.

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.
Review: Anomalocaris (CollectA)

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: Opabinia regalis (Scientific Models by Trilobiti Design)

Review and images by bmathison1972, edited by Suspsy
Opabinia regalis is an enigmatic arthropod (or arthropod-like animal) from the Middle Cambrian Burgess Shale Lagerstätte of present-day British Columbia. It was a benthic predator, scouring the bottom of the Cambrian Seas for soft-bodied prey nearly 505 million years ago.

Review: Opabinia (Soft Model by Favorite co.)

This model is reconstructed with ample attention to detail for this alien-looking wonder from the Cambrian.
I’ve had a soft spot for the weirdos in nature since my early childhood, so Opabinia has always been a favorite of mine. This 3 inch long stem arthropod was a denizen of the ocean floors during the middle of the Cambrian Period, about 505 million years ago.
Review: Opabinia “Oakley” (Paleo Pals)

However you look at it, Opabinia was a remarkably odd-looking creature – so it’s a natural choice for a big cuddly plush toy, right?
I’m guessing most people wouldn’t look at a five-eyed worm with a snaggle-toothed trunk and react with, “Aw, how cute!” Granted, most people aren’t paleontology nerds, either, so your mileage may vary in perspective.

Today, we will be looking at an overview of the Cambrian Creatures Mini Model collection released by Favorite Co. Ltd. in 2016. It consists of eight smaller models representing primarily Cambrian invertebrates along with one chordate.
Review: Anomalocaris (The Great Old Sea by Takara Tomy A.R.T.S.)

Review and photos by bmathison1972, edited by Suspsy
Today we are looking at Anomalocaris canadensis from the 2020 Takara Tomy A.R.T.S. set called The Great Old Sea. It is one of three figures in the set; the others being the trilobite Olenoides serratus and a coelacanth (which I presume is extant?).
