例えばエーギロカシス(1)、フルディア(2)とパーヴァンティアはいずれも縦長い甲皮だが、前部付属肢は大きく異なり、前者は外洋性の濾過摂食、後者は底生生物を摂るのに適した形である。どころか、フルディアだけでも甲皮が横に広く特化した種もある(2, 右下のHurdia triangulata)。

i think specifically for this boi its important to mention that its based on an old very inaccurate reconstruction, as hurdia would be a lot more like aegirocassis

Pahvantia hastata, a hurdiid Radiodont from what would eventually become the Drum Mountains of Utah, some 504 million years later. Done for as a thank you for a Hurdia victoria model.

A Hurdia finds itself stranded on a hot Cambrian beach after a storm, devoid of scavengers.

(I’ll post decent art once I get out of this occasional art-block. Maybe some bromacker stuff soon.)

They also might have used their head shields to court mates; the head shields were probably too soft to be used for much, but could have been bright coloured to attract mates. Below are a reconstruction of a colourful Lyrarapax, and a bent Hurdia head shield. (2/2)

Wiwaxia corrugata of the Burgess Shale, eating Cyanobacterial mats of Morania from the sea floor with a rasping mouth. Behind it, the decaying moult of Hurdia, encrusted by Morania (based on USNM 57718). There are many species of Wiwaxia.

A redraw of “Hurdia megamouth”, an as of yet undescribed species of Hurdiid currently being worked on. As my personal nickname for it suggests, it’s mouth was massive. Excited for the description.

The Burgess was home to several genera of Hurdiid anomalocarids, which survived by filtering food out of the fine silt, brine seeps, and water column, using comb-like frontal appendages. These include Peytoia, Stanleycaris, two species of Hurdia, and Cambroraster elsewhere.

“Put Hurdia triangulata through DeepDream on low settings, it’ll stay pretty much the same”
>destroys Hurdia and turns it into a seal looking thing

Also, first illustration of Lobopodian Ecdysis?
