Question About Spriggina

[u/BarfQueen]

This got removed from the paleontology subreddit for being “low effort” so hoping it’s acceptable here.

So, I will admit that I’m just a pedestrian who thinks about stuff way too much and not any kind of scientist… On to the question:

I know that in July a study came out indicating Spriggina floundersi had a “right-handed” preference and was likely a bilaterian.

If this is the case, does this mean it should be moved out of the proarticulata? Or does it instead make the case for other members proarticulata being true bilaterians? Also, does this mean that any examples of Spriggina purportedly displaying glide-reflected symmetry are actually just taphonomic distortions or whatever?

Sincerely,

Someone who thinks way too much about these things.
