The first arthropod relative with parental care?

[Halichoeres]

A fossil of an adult Fuxianhuia protensa with four identically-sized young is being interpreted as evidence of parental care in the arthropod stem-group:

This is a pre-print, so it hasn't been peer-reviewed yet. Others may disagree with the interpretation: https://www.biorxiv.org/content/early/2018/02/16/266122

Cool fossil, in any event.

Not exactly a stretch, parental care is fairly common in arthropods outside of insects. Interesting to see some potential evidence for this so early on.

I am amazed by such a small and primitive invertebrate dedicated to parental care.

Quite an interesting looking critter. Definitely one I'd like to add to my collection someday, if ever made. Absolutely fascinating that it cared for its young to some degree as well.

Really an interesting article. I love expanding my knowledge about prehistoric times by articles like these. Fascinating.
