This #FossilFriday: a spectacular 3D reconstruction of Waptia fieldensis, an arthropod from the 500 million year old (Cambrian) Burgess Shale, produced by Lars Fields. To learn more, visit doi.org/10.1098/rsos.... 😃

Not Friday here yet but might be busy so here is my contribution: Isograptids from Victoria, Australia. One might even be Isograptus victoriae! Ordovician black slate, from one of the best graptolite stratigraphies in the world 😀 #FossilFriday #EarthScience #geoscience 🧪⛏️

The September equinox occurs on Tuesday at 04:19 AEST (Monday at 18:19 UTC).

🧪Thinking about restarting a print-on-demand store for nerdy geoscience graphics to keep my mind busy while I'm out of action for extended medical treatment. Not so much art as quirky graphics. What objects would be most popular for xmas stockings? Mousepads/Playing cards/etc? #SciArt #geoscience

Not quite Friday yet but will be offline. Here is an internal cast of a brachiopod cut open to reveal the nature of the fill but it reveals something else. Can you see what it is?

Out today in @commsearth.nature.com from some of my newest colleagues at UMMP: evidence that the extinction of dinosaurs led to fundamental shifts in terrestrial environments, and that this signal is recorded in facies shifts tied to the K-Pg boundary: www.nature.com/articles/s43...

Spring in southeast Australia is very nice today. Here are some of the 80+ flowers in our garden today:

Should we be excited about the recent results from Mars? Absolutely! But we also need to understand exactly what they do, and do not, mean. 🧪🔭

🧪⚒️ I think this is interesting but has anybody done any serious thinking about how life might occur and evolve in non-water chemospheres, for example the surface of Titan? Water seems fundamental but is it the only way? www.seti.org/news/life-in...

It's the battle of index minerals today! Both are informative, both have use as gems, and both can be blue, but only one can advance to the next round. Head to mineralcup.org and vote for one today! #geology #mineral #MinCup25

Up at 3.15 am eastern Australian time to watch the lunar eclipse. We saw it to about 90% extinction when thick black clouds rolled in and that was that. Did not see totality or anything after that 🤬☁️☁️☁️☁️☁️☁️🌘☁️☁️☁️☁️☁️☁️☁️☁️☁️🌨️

Keeping cats contained is safer for them and safer for the environment. This is a massive issue in Australia 🧪 The #biodiversity crisis is existential for humanity. www.abc.net.au/news/2025-09...

🧪 #SciComm guess where I live 😂 “…the study found venom from northern populations – found in Queensland and parts of the Northern Territory – and all other brown snake species, formed fragile blood clots at lightning speed during the coagulation process.” www.abc.net.au/news/2025-09...

🌾 Climate change and crops New research shows climate change makes crop yields swing more wildly year to year. Hotter, drier conditions boost both heat stress and water stress, raising global food insecurity risks. 🔗 doi.org/10.1126/scia... #SciComm #ClimateCrisis #Food 🧪

Did Marco Polo’s dad abscond with an ancient Chinese tomb statue? Lead isotope analysis suggests that might be how the Lion of Venice got to Italy in the 13th century. 🏺🧪 (Study published today in @antiquity.ac.uk.)

A new report on Australia’s research sector shows research funding is completely inadequate with major gaps in knowledge and training in demography, technology and AI, climate science and solutions and geosciences. @aunz.theconversation.com

Previously only seen at Dinocon- two new Palaeoplushies make an appearance! The famous Anomalocaris, and the jawless fish Zenaspis! These two are available for the first time over on my website! www.palaeoplushies.com

How does the alvinellid worm Paralvinella hessleri survive the toxic extremes of deep-sea #HydrothermalVents? A new study shows that it detoxifies its environment by forming orpiment minerals inside cells; this unique #biomineralization is a novel adaptation to toxic environments.🧪 plos.io/3HtVCZ6

There are now an estimated four million guns in Australia — more than there were before the Port Arthur massacre in 1996 — and more people licensed to own them #NoGuns theconversation.com/whats-behind...

I recently watched an episode of Alien Earth, which I have been enjoying, but was disappointed to hear a main character attribute the quote "Any sufficiently advanced technology is indistinguishable from magic" to Isaac Asimov when in fact it was AC Clarke who said that. How did that get through?

Climate change is really expensive

6 years ago today the largest California earthquake in 20 years occurred northeast of the town of Ridgecrest. This video talks about the surface effects, shaking, and aftershocks from that #earthquake. 🧪

Wait for it... 👀

🧪⚒️ Just reposting an invitation to listen to the latest Geology Bites episode on the origin of continents. Adding the 🧪⚒️ icons this time. Renée Tamblyn raises fascinating questions about the Archean water cycle and the role of molecular H in powering the first life forms - the archaea.

Using sunlight, rather than electrolysers, to split water into hydrogen has been a dream since the 1960s. A Fortescue-backed pilot plant is hoping to make that a commercial reality.

An interesting contrast in the afternoon winter's light...

On yesterdays #paleostream we covered the Gogo formation, a diverse assemblage from the Devonian of Australia. It is an extremely productive formation with high levels of preservation, giving us stull like the oldest preserved heart and placoderms mid birth.
