Happy #FossilFriday with a depiction of the newest #rangeomorph genus #Aninoides which is only known from the #Ediacaran of #Newfoundland & my attempt at depicting it on the microbe-dominated seafloor along with #Charniodiscus procerus lurk. This painting didn’t make the cut for our paper.

I searched high and low for these images of frond-like chevron marks for comparison with similar structures from the #Ediacaran #Dongpo Biota. too late for our paper doi.org/10.1016/j.pr... @hyperpycnal.bsky.social but here they are anyway. #Fermeuse Formation, Bonavista Pen. Newfoundland

In the #Ediacaran the UK & #Newfoundland were geographically close & share some faunal elements including Primocandelabrum. Tho’ Charnwood Forest “Primo”specimens have #Rangeomorph branches. Charnwood is currently being considered as a possible UNESCO #Geopark so here’s a UK “Primo” on #FossilFriday

This #FossilFriday I’m sharing a lovely#Ediacaran Hiemalora from Conception Bay North #Newfoundland. A rather atypically wiggly one. They are most likely holdfasts of something, but it’s a bit of a mystery what. They are known from about 570Ma to 550Ma This one is from the Trepassey-Fermeuse Fmn.

Happy Fossil Friday! This weeks offering is news that the Inner Meadow site is now 774 sq ft. comparable to the main E -Surface at Mistaken Point & much more diverse. We also found the first convincing #Hadryniscala which has small lateral bars on a strap like form a bit like a seaweed.

The animations @kiabugboy.bay.social produces are next level!

Happy #FossilFriday!! Today is brought to you by superposition of #Ediacaran fossils. Throughout Avalonia the genera that lie atop other frondose organisms are Arborea & Primocandelabrum. Fractofusus overgrow ivesheadiomorph necromass but #rangeomorpha like Charnia and Trepassia never overlie other

Today (or at least this morning, before it turns to Canada Day) is Memorial Day in Newfoundland, marking the anniversary of Beaumont Hamel, the 1916 battle that saw the Newfoundland Regiment get virtually wiped out by enemy fire as they crossed no-man's-land... en.wikipedia.org/wiki/Memoria...

In my latest article for @arstechnica.com I write about a new study that looks at the competition between the process that *reduces CO2* over geological timescales, versus organic carbon weathering, which *emits* CO2 over a similarly long timeframe. ⚒️🧪 arstechnica.com/science/2026...

Feedbacks upon feedbacks: Rock weathering and the climate

Rock weathering may release or draw down carbon dioxide—it depends on the rock.

Happy #FossilFriday from the #Ediacaran of #InnerMeadow. This week i would like to share something newly uncovered & new to the site large deep disks, and the charniid #Rangeomorphs Trepassia sp and Charnia gracilis lying next to one another as they have for 551 million years. What a privilege!

The highlight for me from my work clearing at #InnerMeadow was this complete #Beothukis mistakensis. There’s only 4 or so complete specimens known of this #Ediacaran rangeomorph. It is almost identical to the holotype that we published on in 2020. We interpret it as growing along the seafloor.

today at #InnerMeadow was mainly spent splitting erratics in the holes in the surface that were too large to carry. I channeled skills of my forebears who were coal miners and stone masons in the north of England. The satisfaction of splitting the boulders with hand tools was very satisfying!

Gigantoproductus brachiopods and colonial corals in Carboniferous limestone from Kilkenny County, Ireland. Irish Hunger Memorial, NYC. Some argue these large brachiopods had photosynthetic symbionts, just like the coral: air.unimi.it/retrieve/a83...

I’m a bit late to #FossilFriday today as I’m in the field (literally) clearing at Inner Meadow. But how about a lovely Charnia gracilis to be getting on with. From #InnerMeadow of course.

Douglas Adams had it so right. It's not about the answers we can generate It's about the questions we can ask

Happy #FossilFriday which is this week brought to you from the #Ediacaran MUN Surface in @discoverygeoparknl.bsky.social . The exceptional preservation that characterizes that surface is well seen in this ? #culmofrons. A #rangeomorph with branches showing only one 1/2 of the biserial form.

Absolutely overjoyed to share our new paper describing the oldest occurrence of soft-tissue preservation in crinoid echinoderms and their ecological significance 🧪

Exceptional soft-tissue preservation reveals the oldest evidence for tube feet and their ecological significance in crinoids

Abstract. Tube feet are extensions of the echinoderm water vascular system that play essential roles in feeding and ecology in living crinoids. However, on

I had a fun day out yesterday in @discoverygeoparknl.bsky.social sharing the #Ediacaran fossils of Capelin Gulch & the Johnson Discovery Surface with delegates from GAC-MAC 2026 in St. John’s. Great discussions on the rocks & the snow even held off for us! Thanks to all leaders delegates!

This #FossilFriday is brought to you courtesy of the lively new #Ediacaran #rangeomorph Aninoides coombsorum named by @simonrosse.bsky.social. Currently only known from the 551Ma Inner Meadow Lagerstätte in Newfoundland. Same age as the youngest White Sea type biotas in Australia, Russia etc.

👀 shameful.

Benjamin Gill@sedgeochem.bsky.social · 2mo ago

Yep... I seriously don't have words...

This one is well worth a read for anyone interested in the Ediacaran

Excited to share our new paper out today in Science Advances describing some familiar Ediacaran fossils (beautifully reconstructed by Alex Boersma) in an unfamiliar place! www.science.org/doi/10.1126/...

Discovery of White Sea assemblage fossils from Laurentia

Fossils of early animal groups found in deeper-water settings millions of years earlier than previously understood.

Happy #fossilfriday from the #Ediacaran at #InnerMeadow at 551Ma it is the youngest known example of the “Avalon Assemblage” (equivalent to the youngest “White Sea Assemblage”). The field season is underway here in NL. We continue to remove soil & fossiliferous rocks from over the fossil surface.

My recent cohort of doctoral students started getting requests to review papers and asked me an interesting question. The paper for review is close to their expertise but does that mean they have a conflict of interest? Peer review is important service you should engage with as much as possible… 🧵

Happy #FossilFriday from the #Ediacaran at #InnerMeadow. I’ve been focussing on removing boulders and soil the last couple of weeks but this beauty popped out. It is a scan of the natural cast of the base of a large #Aninoides

I feel like posting a #notafossil for #FossilFriday necessitates posting a fossil too. Yesterday Helena and i did some clearing at #InnerMeadow. Mainly just removing the thick soil & not getting down to new fossils until the end of day when the surface was wet and light flat (so no 📷) but we did..

Happy #FossilFriday from the late +Ediacaran where I (disappointedly) want to share the most remarkable pseudofossils I have ever seen. This beautiful #conulariid or protechinurus like thing (bottom) and 2 longitudinal striated tube/like things are all sub glacial scratch marks.

As tempting as it is to spend all my time in the field at Inner Meadow. This week i went on an Ediacaran adventure up the Bay de Verde Pen. with @jeffontherock.bsky.social looking at the post #KotlinCrisis interval at beautiful sites on the barrens. Access is more open after devastating fires last…

has anyone seen one of these before? It is in a Newfoundland #Ediacaran mudstone found with @jeffontherock.bsky.social today. It looks a bit like beetle boring in wood. Maybe @ichnologist.bsky.social has seen something like it. burrows on the same bed are positives, this is a negative feature.
