Description
A couple of Cambrian lobopods I drew to accompany a short article on my website about Anomalocarids. In my article, I hypothesized that lobopds and anomalocarids may have descended from a common ancestor based on morphological similarities between the two.The animals are (clockwise from top): Microdictyon sinicum, Hallucigenia sparsa, Onychodictyon ferox and Aysheaia pedunculata.
Note, by the way, that what appear to be "eyes" on Microdictyon, Hallucigenia and Onychodictyon are actually sclerotized armor plates.

Hello there. I would like to show this art in my prehistoric pet project. Fully crediting you of course. Also i would like to know what did these animals eat?

Are the small appendages on the front of the animals sensory organs similar to antennae?

"In my article, I hypothesized that lobopds and anomalocarids may have descended from a common ancestor based on morphological similarities between the two" - This is surely wrong, as the later are known to be derived from the former.
"Note, by the way, that what appear to be "eyes" on Microdictyon, Hallucigenia and Onychodictyon are actually sclerotized armor plates." - Those are known to be sclerotized true compund eyes.

With the first part, I meant that anomalocarids and lobopods that are contemporaries (such as Anomalocaris canadensis and Hallucigenia) are descended from a common ancestor much in the same way that humans and chimps are descended from a common ancestor.
Actually, has there been definitive proof that anomalocarids developed from lobopods? At the time I wrote that article I couldn't find any hard evidence, but I'd love to see some if anyone has uncovered some new fossils.
And is there actual evidence that the "eyes" on Microdictyon, Hallucigenia and Onychodyctyon are indeed true eyes? The book I got that information from said they were sclerites, but there could be new evidence that I haven't read yet. I'm always looking to refine my knowledge of prehistoric life.

Interesting.
Hallucigenia and Aysheaia I'm already quite familiar with. I'm not so familar with the other ones though. Perhaps I'll look more into lobopod info.

I like the colors, they're oddly convincing. reminds me a bit of sea slugs.

They're so colorful! Never seen those colored like this.

Isn't the primary reason for the hypothesis of lobopods and dinocarids sharing a common ancestor is because of both groups having "lobe-feet"?

That's the biggest one that I've seen. Also, many of the Sirius Passet dinocarids like Pambdelurion and Karygmachela have segmented, lobopod-style bodies (admittedly, however, they could just be highly-modified lobopods rather than primitive dinocarids). Unfortunately, I don't think there's enough evidence to definitively link dinocarids and lobopods. Really, I was just having some fun doing a little speculation. I did, however, highlight the fact that the statements on my website were only my own opinion (backed up by some evidence) and not scientific fact.
