Yet another new #FossilFriday paper! This time just me, but building on work from the MUN Paleobiology Crowd over a number of years.
This OA paper outlines the lines of evidence used to determine mode of life of the #Ediacaran #Rangeomorpha. Always careful and objective we work with one

broad Charnia frond at the bottom with a narrow frond right at its tip lying in the same orientation

This #FossilFriday is brought to you from the #Ediacaran of #InnerMeadow with the observation that #Charnia brasieri sometimes have #Trepassia like little feathers on top of their fronds. Part of a review paper coming out next week on life attitude of rangeomorphs :-).

Comparison of the frondose features in the Dongpo Formation with uninterrupted chevron marks (A−D) and the Ediacaran Charnia for comparison (E). (A) Uninterrupted chevron marks from the Carboniferous Gull Island Formation, Ireland (modified from Doyle and Hoey, 2022); (B) and (D) frondose forms from the Dongpo Formation (modified from Wang et al., 2026); (C) uninterrupted chevron marks from the Lower Silurian Aberystwyth Grits, Wales (modified from Dżułyński and Walton, 1965); (E) Charnia ewinoni from the Ediacaran of Newfoundland (modified from Pasinetti et al., 2025). All scale bars are 1 cm. Portions of the branch-like structures highlighted in (B-D), primary branches in (E) are offset not opposite and have second (red) and third order branches (green) highlighted as is typical of Ediacaran rangeomorphs.

Earlier this year there was an article on the beautiful new #Ediacaran #Dongpo Biota in China, it has some lovely fossils in it. Well worth a look!
There were also some things interpreted as fronds that we consider to be abiogenic uninterrupted Chevron marks. doi.org/10.1016/j.pr...

unnamed elongate Arboreomorph frond with broad flat disc numerous small branches arise from a central axis at a high angle

reconstruction of an elongated frondose arboreomorph organism with an inferred upright mode of life. Depicted on a hypothetical deep marine seafloor with patchy white microbial communities

coming soon another new Ediacaran taxon from Newfoundland. This one is an #Arboreomorph from the #Ediacaran of the NE Avalon Peninsula discovered and written up with PhD students Pascal Olschewski @simonrosse.bsky.social. The art needs some work to do justice to the fossil but Happy #FossilFriday!

This #FossilFriday, how about a little look forward in the #Ediacaran to the post Kotlin Crisis extinction event strata in in Newfoundland. doi.org/10.1130/G542...

The post-extinction biotas are dominated by discs such as #Aspidella terranovica and the giant protistan #Palaeopascichnus.

A big post this #FossilFriday, folks! We've just published our paper describing the age of the #Ediacaran Inner Meadow fossil site in #Newfoundland, and it has VERY important ramifications about what we (think we) know about extinction in the Ediacaran...

Happy #FossilFriday we just got page proofs of our paper on the diversity and geochronology of our #InnerMeadow site so let’s celebrate by sharing the first #Erniettomorph from the #Ediacaran of Newfoundland, #Phyllozoon (right) with a bonus #Bradgatia top left.

long narrow arborea sp. frond with flat round disc

detail of branching in arborea and junction with the disc

Happy #FossilFriday from a wet cold La Niña Newfoundland. How about a new #Ediacaran fossil teaser, from a brand new fossil site north of St. John’s? This is one of several remarkable fossils that came out of a rockfall and discovered by my PhD student Pascal Olschewski. A new species of #Arborea!

This #FossilFriday: a wonderful new piece of research based on the #Ediacaran fossils of #Newfoundland. The name Aninoides is derived partly from the language of the Beothuk, the indigenous people of Newfoundland. Please read below to learn more!

three images of a leaf shaped fossil with low angle first order branches and fractal like higher order branches left is photo of a replica (mold of the lower surface) middle is interpretive drawing and right is a plan view of the inferred top of the same fossil

photo of holotype of Aninoides coombsorum super mature specimen with long first order branches. looks a bit like a comet below is interpretive drawing of the same. disk is accidental not associated with the fossil itself

retrodeformed image of Aninoides coombsorum super mature specimen after retrodeformation see ellipse bottom left which was originally a circle

Our final #Ediacaran palaeontology paper of the year! Introducing #Aninoides coombsorum gen et sp nov

Such a beautiful fossil. At the moment only known from our Inner Meadow site, Newfoundland. Paper led by PhD student Simon Rosse-Guillevic

ediacaran frond with long first order branches like the tail of a comet the disc at the base is accidental

small specimen of a new Ediacaran rangeomorph genus, leaf shaped with long primary branches and no basal disk

seafloor reconstruction of the Ediacaran showing a procumbent frond growing along the seafloor among microbial matground fabrics. Depicting the darkness of the deep marine, in the distance are charniodiscus procerus with their procumbent stem and upright cone like frond

This #FossilFriday I am teasing some images of a forthcoming new Ediacaran genus. It is a relative of #Charnia which has hogged attention these last 3 years. My PhD student Simon is lead author. It lived on the deep dark ocean floor of the #Ediacaran Fermeuse Formation in Nfld (Inner Meadow).

This #FossilFriday, here's the holotype of the #Ediacaran organism Charniodiscus concentricus from Charnwood Forest in the UK. The illustration and colour coding reveal how the organism's branches were actually preserved on different bedding planes. From doi.org/10.3389/fear...

a comet shaped fossil on a bedding plane with cm scale bar. has an accidental disc on one end. it has very long branches at a low angle to the axis composed of smaller branches similar to #Charnia

This #Ediacaran #FossilFriday beauty was uncovered the 1st day Inner Meadow. We are so looking forward to sharing this one with the world. A new genus related to #Charnia (in press) it will be named for its comet-like shape, but the disc here is accidental (none of the other 9 specimens have it).

what a great crowd out to learn about #Charnia brasieri at the GeoCentre tonight and the celebratory cake from emthefairycakemother.
I can confirm that C. brasieri was delicious. I’ve decided that #Ediacaran organisms became extinct because they tasted so good.

Leaf like fossil with zigzagged axis branches meet the axis at a steep angle, are curved (falcate) with transverse second order branches

This week I found a partial #Charnia brasieri hiding in plain sight 🥷 in the cast of the #Ediacaran Mistaken Point E Surface that is housed at @johnsongeocentre.bsky.social where I’m giving a talk about C brasieri on Monday! Happy #FossilFriday
