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 :-).
leaf shaped fossils of Charnia brasieri and Trepassia sp.

Happy #FossilFriday how does a thread about the Inner Meadow biota and unexpected age for the fossils, and a refocusing of Martin Brasier’s #KotlinCrisis sound?
We’ve been trickling out our findings from Inner Meadow including #Charnia brasieri, #Aninoides and there's even cooler stuff in review. 🧵
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).
Digital cel-shaded art of a wibbly wobbly Dickinsonia, a weird wobbly lifeform from before the Cambrian era. It looks like a floppy frisbee with bilateral lines sectioning its body into many gelatinous ribs. It lives underwater surrounded by fleshy ‘plants’, including orange charnia with spots and neon green hylaecullulus. Since I’ve interpreted Dickinsonia as a transparent creature, the other life forms can be fuzzily seen through its body. This little scene is set on an isometric square chunk of sandy seafloor.

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
specimen of C grandis showing rhomboidal branching plaster cast at The Rooms
opposing leaf like charnias parallel to current so not felled but growing along the seafloor in our opinion
schematic showing the 1st and 2nd order branches of all the charnia species
Some more #Charnia content this #FossilFriday, but this time Charnia grandis reins. stat. It had been synonymized with C.masoni and mostly used for gigantic specimens of what is now C.brasieri but its strange rhomboidal branches are very distinct. the 1st branches are 45o and 2nd are at 90o
leaf shaped animal fossil with sickle shaped branches meeting a a zigzagged axis Charnia brasieri sp nov
Shaped of the currently valid species of Charnia and their branch types
seafloor reconstruction of Charnia brasieri as a procumbent organisms living among microbial matgrounds
This #FossilFriday I’m excitedly sharing a new #Ediacaran #Charnia brasieri named for my PhD Supervisor & friend Martin Brasier who died 2014. I’ve wanted to name something for him ever since but I wanted it to be something special. When I saw the first one from Inner Meadow I knew it was the 1 🧵
two charnias lying in a matground the fronds are living reclined on the seafloor (procumbent) and have falcate primary order branches that we interpret as having curved up above the seafloor, becoming the classic charnia shape in 3D
This is such a beautiful fossil to work with. As soon the first specimen appeared i loved the architecture & pulled rank, calling dibs on working on it (which i seldom do). This is the artwork of our new #Charnia that i produced for the journal to go in the graphical abstract.

fossil with alternating falcate branched with 2 orders of smaller rangeomorph branches. it is a negative relief on top of a grey siltstone.
Happy #FossilFriday from the #Ediacaran of Newfoundland and our #InnerMeadow site, teasing this beauty of a #Charnia which will get a name any day now. This specimen was found just a couple of weeks ago (after acceptance of the paper) & is c. 35cm long & 8cm wide (before retrodeformation)…,,
Happy #FossilFriday from the #Ediacaran of Inner Meadow in Newfoundland. The meadow is beautiful this time of year and it is great for the clearing work. Here is a newly exposed #Charnia masoni. The first masoni from this site, our faunal list is getting long!
spindle shaped fossil with zigzagged central axis and numerous j shaped branches with fractal-like subsidiary branches.

Happy #FossilFriday from the Ediacaran of Newfoundland. For your enjoyment here is a specimen of the most common form of (as yet undescribed) #Charnia from our Inner Meadow site of #Ediacaran age in Newfoundland. It has J shaped branches and i particularly love the arcs the secondaries describe.
30+ cm long charnia gracilis, a long narrow frond like a spear point with 3 clear orders of branching from Inner Meadow, Newfoundland
seafloor reconstruction of reclining charnia on an Ediacaran seafloor surrounded by microbial matgrounds that are partly eroded, in some views you can see the open nature of the structure when sculpted using the brasier model. The competing pneu model of seilacher produces something like an inflatable mattress.
#Charnia has been one of my favourite fossils since I saw a cast of it in an undergrad lab. it has been a privilege to be able to work on it these last couple of years. Partly through new #Eduacaran material at Inner Meadow but with my 3D reconstructions allowing us to envisage how little biomass
three leaf shaped charnia masoni nestled in a partly eroded deep marine microbial mat
This #Fossilfriday i’m going to share a little #sciart adventure with #Charnia masoni which comes from the Charnwood Forest Geopark in the UK. The models are those i created using Martin Brasier’s rangeomorph architecture rules.

Another #FossilFriday and another Charnia paper out in the wild from Mun Paleobiology. This is a rare Mcilroy sole author paper mostly i publish with my students, but this was a solo adventure.
The paper shows how #Charnia masoni was constructed in 3D. Sculpting took about 100 man hours. …

Charnia sp. an elongate #Rangeomorph frond from the #Ediacaran of Newfoundland, Canada in Discovery UNESCO global geopark
Happy #FossilFriday from the #Ediacaran of #DiscoveryGeopark and a beautiful little #Charnia. The fossil is actually up above the bedding plane suggesting that it might be a cast of the inside of the upper surface of the frond. That might account for the “loose”branch architecture.
here are some 3D views of my #Ediacaran #Charnia sculpt in progress. Video grabs for discussion with colleagues really but some of you might be interested in them.

The preprint of my OA paper on #charnia is available online already.
This was the most fun thing i have done in my 30 years as a palaeontologist.
I think it is straightforward to follow it builds on the architectural concepts of brasier et al 2012.
This #FossilFriday, the first fossil identified at the new #Ediacaran aged fossil locality in Upper Island Cove, #Newfoundland. This #Charnia is only the tip of a massive iceberg: we can't wait to start sharing the results from this remarkable site!

the branch architecture of the reclining rangeomorph Charnia masoni showing the shapes of the first and second order rangeomorph branches. The paper which should be out shortly has the 3rd order.
This #FossilFriday i am excited to tease a new piece of work in press on the architecture of #Charnia masoni from the #Ediacaran . I basically took the rangeomorph architectural rules established by my mentor Martin Brasier and sculpted them in 3D with beautiful consequences. 1/2
