A Jaekelopterus rhenaniae illustration has been commissioned by team members at Everything Dinosaur. This drawing will be used in a sea scorpion fact sheet. The fact sheet will be sent out with sales of the new CollectA Deluxe Jaekelopterus figure. This eurypterid model is due into stock in the spring of 2025 or thereabouts.

Jaekelopterus rhenaniae
J. rhenaniae is the largest known eurypterid described to date. It is also possibly the largest arthropod to have ever lived. The size of this enormous invertebrate has been calculated based on a fossilised partial chelicera (pincer) from the Early Devonian Emsian Klerf Formation (western Germany).
The fossilised pincer measures over thirty-six centimetres in length. If complete, palaeontologists have estimated that this appendage would have been over forty-five centimetres long. Based on a body length to chelicera ratio found in other pterygotid sea scorpions, scientists have estimated that Jaekelopterus rhenaniae was over two and a half metres long.

It was probably an apex predator. It probably fed on other invertebrates as well as primitive fish. The CollectA Deluxe 1:20 scale Jaekelopterus model is supplied with a small figure of a jawless fish that the giant sea scorpion has captured.
The new for 2025 CollectA Deluxe Jaekelopterus figure complete with a pteraspidid fish victim.
The fish prey represents a generic jawless agnathan. It is probably based on a group of prehistoric fish called a pteraspidid.

The CollectA Deluxe Jaekelopterus figure is estimated to be around sixteen centimetres in length. At this size it would fit with an approximate scale of 1:20.
Commenting Upon the Jaekelopterus rhenaniae Illustration
Mike from Everything Dinosaur commented:
“We chose to commission a lateral view of the Jaekelopterus figure. This gives us the opportunity to add a human figure next to the model. The addition of this human figure will instantly provide a scale and give viewers an immediate impression as to the size of this giant invertebrate.”
