Darren Naish and Richard Forrest (RIP 2026) at the Square Tower, Portsmouth, 2001. An especially bad photo. I don't recall who took it.

I've known Richard since the 1990s and he was a mentor, advisor and friend to many of us. He did a massive amount to build collabs, help in excavations and pass on advice and enthusiasm. He was a warm and welcoming person who promoted inclusion, collaboration and the role of amateurs in science.

Plesiosaurus dolichodeirus scavenges a dead pterosaur A gloomy image of the elasmosaur Albertonectes foraging in the deep sea. "Plesiosaurus" macrocephalus, a species known only from a famous but poorly studied juvenile specimen, and its possible parent: a mature rhomaelosaurid. Elasmosaurid Thalassomedon surfaces to take a breath. This image shows what you may have actually seen from a boat while marine reptile watching, once we consider the physics of how plesiosaurs moved and floated.

All plesiosaurs today for #FossilFriday, in tribute to our departed friend Richard Forrest.

In shock to hear that Richard Forrest passed this morning. What a guy. I've met few people as enthusiastic about fossils. He had a whole life, whole career, outside of the academic world but made huge contributions to scholarship. And was so kind and welcoming to everyone. RIP.

Just learned that Richard Forrest, one of the pillars of British vert palaeo, has passed away unexpectedly. Richard was such a friendly, welcoming person, an expert on British marine reptiles, and the unofficial custodian of SVPCA. We spent many hours chatting in various pubs. He will be missed.

An absolute pillar of the British vertebrate palaeontology, plesiosaurus expert, Richard Forrest, passed away. Really sad to see another senior welcoming figure in this field, leave us. Was lovely working with him while in Lyme Regis.

Richard Forrest (RIP Jan 2026), with Mike Taylor behind, September 2017. A group of palaeontologists following a Scottish, post-SVPCA fieldtrip of (I think) 2007.

Richard Forrest (RIP Jan 2026) at right, with Darren (left) and Neil Gostling (centre) during July 2025.

Via Sally Hollingworth and Sue Forrest comes the unexpected news that Richard passed this morning. This is a shock and a major loss. Richard is a notable person in the Mesozoic research community, known for his work on marine reptiles and his role in organising conferences and meetings. Very sad.

A gorgeous taxidermy striped possum on display in the Haus der Natur in Salzburg

Australia has no woodpeckers, but striped #possums are tropical #marsupials that do the same job: their big ears detect beetle grubs tunnelling in wood, which they chip out with large incisors, then use their elongated 4th finger to hook them out of the tunnels (just like aye-ayes do in Madagascar).

Microscope photo of a slice of rock with white light shining through it. The rock is composed of a polygonal mosaic of mostly white crystal grains, light brown crystal grains, black crystal grains with a white crystal in the centre,  and dark brown organic matter. A red scale bar shows the image is about 0.5 mm across our 500 microns. Microscope photo of a slice of rock with cross polarised light shining through it. The rock is composed of a polygonal mosaic of mostly grey crystal grains, light brown-grey crystal grains, black crystal grains with a bright blue crystal in the centre, long thin orange grading to pink crystal grains, and dark brown organic matter. A red scale bar shows the image is about 0.5 mm across our 500 microns. The image has been rotated approx 45 degrees anti clockwise.

A 1.4 Ga organic rich mudstone from Australia that has low-grade contact metamorphism. Black blobs with crystal cores are thucolites, brown square is a fragment of microfossil that has been partially mineralised. More deets in alt text. #ThinSectionThursday #Geology #paleontology ⚒️🧪🔬

#FossilFriday One extra fossil from Singapore, in the black limestone cladding of the same Prada shop as the rugose coral posted earlier, a brachiopod preserving internally the calcite supports of the two arms of the lophophore visible as rings of dots on the left and right side of the fossil.

The resignations of Tim Davie and Deborah Turness must be an opportunity for the BBC to turn a new leaf, rebuild trust and resist those like Nigel Farage who want to destroy it

We must stand up for a strong, independent BBC, to stop Trump’s America becoming Farage's Britain.

Specimen of carletonite with prisms of blue and pink all around. There is one large square crystal with a small blue square in the middle with pink on the outside on the upper right side of the specimen. It sits on a black background. At the Canadian Museum of Nature.

It’s Geodiversity Day & Mineral Monday!! So I wanted to show you a rare mineral called carletonite, which is usually bright blue but seen here with a pink zonation. It was discovered here in Canada, at the mineral species rich Mont Saint-Hilaire. #GeodiversityDay #MineralMonday #GeoscienceBluesky ⚒️🧪

Seeing as today is #InternationalGeodiversityDay and as I'm leading a geology walk there later this month, as part of a Charity Day Fossil Hunt, I thought I'd write a blogpost about the geodiversity of Runswick Bay: fossilhub.org/runswick-geo...

Conceptualization of the citational justice toolkit, organized around the
research cycle. In the top right quadrant of the cycle, we start with Planning, which includes the Ideas and Funding stages of research. This section contains two practices: citational politics training module and the Academic Wheel of Privilege, and one tool: the citational transparency browser extension. In the bottom right quadrant of the cycle, we have the Project, which includes Research and Journal Selection stages of research. This section contains one practice: diversify your reading. In the bottom left
quadrant of the cycle, we have the Paper, which includes Paper writing and Submission stages of research. This section contains three practices: citing R packages and other tools,
annotated citations lists and the citational diversity statement, and nine tools: Genderize, the Gray test, the citation audit survey, Mirya Holman’s pre-submission checklist, GBAT, the citational diversity codebook, a template for citing Indigenous peoples, the inwardness
metric and GCBI-alyzer. In the top left quadrant of the cycle, we have Publication, which includes the Peer Review and Publication stages of research. This section contains one practice, the Academic Wheel of Privilege.

Regular reminder to authors to please acknowledge and cite people who have contributed to your work. Yet again I find a paper that I collected data for and I’m not acknowledged. 🧪

Also see our recent paper that provides a toolkit for more just and equitable citation practices👇🏽

I tried to find out if the fossil I bought online was real. Then I realized I was asking the wrong question | CNN It’s obvious a 95 million-year-old fossil would have a rich past — but what a CNN writer discovered about a dinosaur tooth he bought for about $100 was more than he anticipated.

Great to see an interrogation of the sources of commercial fossils, especially from Morocco 🦖🇲🇦

But utterly disappointing to see the platforming of people who have repeatedly and openly flouted (inter)national laws. Not a legal (or ethics) expert in sight 🤦‍♀️ [1]

One of my favourite #MaryAnning facts™️ is that she would discover fossil cephalopod 🐙 fossils with preserved ink sacks, concoct a dangerous chemical slime to turn them back into gloopy ink, and then use her Jurassic ink to draw exquisite illustrations of the vertebrate fossils she found.

I've not seen that one before. It's a beauty! Siphonodendron, I'd imagine; probably Siphonodendron junceum, but I'm not sure how reliable the species classification is.

Our cats Jim and Roscoe looking very serious, in our kitchen.

I enjoy the way that in this photo my cats look like a hip-hop duo quite a lot of people quite liked in 1996 who have made a comeback record, done an interview with a broadsheet newspaper and are attempting to prove they are still serious and relevant.

Photo of some rocks layers - interbedded mudstone and sandstone. Under one sandstone layer, three prongs of sandstone push down into the mud later. This is a dinosaur footprint from a three-toed dinosaur. There's is some green text on the image that reads "three-toed dino footprint" and a dinosaur emoji. Photo of a rock face of layers of sandstone. In the middle is a large depression filled with sand that has squashed the laminated sediments underneath. Text reads "sauropod footprint" with a sauropod emoji. Photo of layers of sandstone and mudstone. In one later of laminated sediments is a depression structure filled with sand. Text on image reads "here. Sauropod stomp". Photo of a rock face, at the base is a rucksack placed as scale. The exposure is layers of sandstone and mudstone. About the quarters up is a depression filled with sand. The laminated layers underneath have been squashed.

Saw some dinoturbation in the Jurassic Sandstones, South Cliff, Scarborough today.

First time spotting these here, was very exciting!
