エディアカラン紀前期のWeng’an Biotaから産出する，動物の胚に似た微化石Megaclonophycusはクラウン後生動物ではなく，コアノゾア（襟鞭毛虫類＋後生動物）では恐らくないホロゾアなのではないかということ．

subtriangular multi branched probably rangeomorph frond bradgatia-like foot for scale
poorly preserved Hapsidophyllas with 2 rows of radiating branches foot for scale
Pascal’s PhD involves describing this rich biota along with a new date hopefully coming at the same time later this year. The rest of the biota are mainly Mistaken Point type fossils but not quite as well preserved though much closer to St. John’s!

Arborea elegans showing long narrow frond with short orthogonal brabches and a wide flat basal disc
Another #FossilFriday and another new Nfld. Ediacaran for you to enjoy hot off the press. Introducing Arborea elegans. This is the first fossil from a rich new site near #Torbay & #MiddleCove just north of St. John’s. An area always considered unfossiliferous, but discovered by Pascal Olschewski🧵

🧵 1/10 New paper out in @natmicrobiol.nature.com from my postdoc at @mib-wur.bsky.social! 🎉
How eukaryote-like was the archaeal ancestor of eukaryotes? Sequence searches alone can't tell us — so we used protein structure prediction to look deeper. 🧬
www.nature.com/articles/s41...
Just over ten years after the discovery of the first Asgard archaeal genomes, we revisit the rapid expansion of this remarkable archaeal lineage. From diverse genomes and metabolisms to eukaryotic signature proteins and the first cultured representatives.

"Demonstrations of reproducibility are not reproducibility" www.nature.com/articles/s41...
Gómez-Llano & De Lisle argue that many recent measures adopted to address replicability and reproducibility in science
may actually undermine these efforts.
