My 25 years of palaeoart chronology...
In 2013 I built 23 scale and life-size models for MUSE Science Museum, in Trento, Italy. Here's Kimberella, from the Ediacaran.

#mollusk evolution hot take:
I'm gonna guess that #Kimberella, the mobile whooping cushion of the #Ediacaran seafloor, was not a mollusk but probably closely ancestral to mollusks. (or at least closely related to something ancestral to mollusk)
It's kind of snail-like and probably had a lick-ey tongue, but it doesn't look like it has the crunchy shell that the original mollusk was projected to have, and I guess the tongue was not quite snail like.

Fascinating.
"[S]cientists have confirmed that they have found the world’s oldest meal – in a fossil of an animal that lived 558 million years ago.
[...]
Kimberella appears to have had a digestive system that was capable of selecting the sterols it needed to absorb into its tissue, while discarding the unusable molecules. “[...] That means that Kimberella already has this pretty sophisticated way of feeding.”" -

Guts, gut contents, and feeding strategies of #Ediacaran animals https://www.cell.com/current-biology/pdfExtended/S0960-9822(22)01699-2
By examining the molecular remains of what the #animals ate, the researchers were able to confirm the slug-like organism, known as #Kimberella, had a mouth and a gut and digested food the same way modern animals do. It was likely one of the most advanced creatures of the Ediacarans.
