A #FossilFriday retweet of our paper on deuterostome origins that came out this week. How can you link these monsters together in a single evolutionary framework? Short answer: with a lot of head scratching and whisky. Long answer: check out the paper. https://t.co/dRbaP9ZlO9

Great @nytimes coverage of @SarahLosso1 and @InvertebratePal's new @MCZpaleo paper on the licentious habits of trilobites. Choice passages: "shroud of mystery," "flexible fingerlike," "shriveled limbs," "spiny backside." Will the scandal never end?

Forgot to add, the program goes live at 11am. If you want a teaser about some of the cool fossils we'll be talking about, check out this blog post I wrote a few years ago (art by @MesozoicMuse ):

The Burgess Shale is known for the exceptional preservation of half-a-billion year old invertebrates which give unique insights into early animal evolution. What can be harder to study are the whole communities in which those animals lived; these studies are time/effort intensive

More evolutionary insights from the #BurgessShale, a new species of Mollisonia described by Aria and @ROMtoronto curator J-B. Caron. I remember seeing some of these specimens before they'd been prepared, absolutely unreal levels of appendage details revealed! #DeepTime

A nice write up by @Laelaps on the new Burgess discovery by Joe Moysiuk and JB Caron @UofT_Palaeo @ROMtoronto. I like how the discovery of is put into the winder context of marine ecosystems during the Cambrian (underscored by @cambriancritter).

Awesome new paper by Joe Moysiuk and JB Caron describing the "spaceship" radiodontan from the #BurgessShale. I particularly like the discussion of feeding ecology, supported by beautiful plates of the appendages/mouth: https://t.co/g7hQl8rqFX

#DeepTime Cambrian ecosystems could be quite complex, with many of the hallmarks of a modern benthic community. The @NMNH dioramas do a great job of showing this, with priapulids like Ottoia and Selkirkia being a major infaunal component. Second image from https://t.co/6UGECm1ICU

#DeepTime Today's Cambrian creatures (find them in @NMNH's new fossil hall opening this Saturday) are Ottoia (first) and Selkirkia (second). These predatory worms had vicious mouthparts covered in teeth, hooks and spines (third). Images https://t.co/ff6Sc6cqCk by @PalaeoSmith

@amiasmatics @NMNH @ROMtoronto The first image is a close up on some of the branchiae, which have a sort of grape-cluster like appearance (Eibye-Jacobsen 2004). The second image is a cross-section line drawing showing where they'd be located (Conway Morris 1979). (2/2)
