Have you ever spotted a rock squirrel (Otospermophilus variegatus)? Found throughout much of the southwestern United States and Mexico, this rodent can weigh up to 1.8 lbs (0.8 kg). While it does forage in the trees, this species prefers to make its dens in rocky terrain like cliffs and canyons.

New #AmniotaLabCollab! 🦌  Three legacy faunal collections from coastal Lebanon🇱🇧 get their first direct dates, building one of the longest paleoecological records in the Levant, spanning ~400,000 to ~100,000 years ago #OA #paleontology Discover more👇 

Lebanese faunal legacy collections uncover 400,000 years of woodland resilience and distinct hominin ecological strategies - Communications Earth & Environment

Mediterranean woodlands persisted in coastal Lebanon for hundreds of millennia, supporting diverse ungulates and shaping distinct hominin foraging strategies, highlighting ecological contrasts with the southern Levant, as indicated by dating, faunal analysis, dental wear, and landscape modeling

New collaborative work from #AmniotaLabCollab! Darío Fidalgo co-authors this study on RVH-1🦴, the first human fossil from the Ruidera site (Spain): a partial parietal from the Middle Pleistocene. Its vault thickness and parietal angle sit within the broad range of 𝘏𝘰𝘮𝘰 𝘩𝘦𝘪𝘥𝘦𝘭𝘣𝘦𝘳𝘨𝘦𝘯𝘴𝘪𝘴

New #AmniotaLab publication! 🌍 The Atbara River, one of the Nile's tributaries in #Sudan, hasn't always flowed where it does today.  Mohammednoor et al found that about 27,000 years ago the river suddenly started carrying sediment from a different mountain region: the volcanic Ethiopian Highlands ⛰️

Review of CH Waddington's influence on developmental biology and evo-devo: journals.biologists.com/dev/article/... includes supp info with his 50th birthday songs!

C.H. Waddington's lasting achievements in development and evolution

ABSTRACT. C.H. Waddington (1905-1975) was a British biologist and perhaps the major figure in developmental biology between the 1940s and 1960s. He is one of the few pre-molecular-age developmental bi...

Yesterday I presented what I think was the first conference poster of my career 😅 at #SMBE2026, talking about my ERC StG project on the genomics of miniaturisation in vertebrates—GEMINI. Really happy for the discussions it sparked. Thanks everyone who stopped by! 🧪

Soon we were developing collaborative work on the fossil record of marine fishes in Egypt. The first project focused on an assemblage from the Paleocene-Eocene Thermal Maximum, a rapid increase in global temperature around 56 Ma (and a potential deep-time analogue to contemporary climate change).

And there's an intriguing hint that low latitudes might have been important for the early diversification of percomorphs. They make up a greater proportion of taxa in faunas closer to the equator during the Paleocene, before becoming a major faunal component at all latitudes in the Eocene.

Meet the long-eared hedgehog! Inhabiting parts of Central Asia, this omnivore feeds on fruit, insects, & small vertebrates. It has been observed rubbing its spines against toads, suggesting it might be using their toxins for its own self-defense. Photo: vladimirblinov ,CC BY-NC 4.0, iNaturalist
