There have been quite a few big earthquakes lately. Are they related? Are we having more big earthquakes than usual? Here’s a quick video addressing some of those questions.

Catching up on a few earthquakes this evening. The M7.6 Drake passage earthquake yesterday appears to have been an intraplate strike slip faulting #earthquake , unlike the M7.4 earthquake a few months ago in the greater area, which was subduction related. ⚒️🧪

Welcome back to #fossilfriday

Here is the fresh water Dastilbe elongatus. This specimen comes from the Lower Cretaceous (Aptian-Albian) Santana Formation in Serra de Araipe, Brazil. The Santana Formation is well known for its exquisite preservation of pterosaurs fossils.

I'm taking my kids to Mt. Orab this weekend to hunt trilobites. It's an Ordovician site (Arnheim Mb. Richmond Fm.) near Cincinnati with Flexicalymene retorsa and Isotelus, though much less common.

I'm hoping to see my little girl find her first complete trilobite.

Quick #FossilFriday #paleoart post: a 2025 redo of my 2019 take on the giant #deer Megaloceros. Palaeolithic art captures some aspects of Megaloceros appearance but the details are not unambiguous: when is a line across a body a stripe, when is it a boundary between colour regions?

Three Megaloceros, a stag, doe and fawn, in front of an ice age landscape, painted in 2025. The bodies of the adults have large blocks of colour, without prominent stripes.

After we published the new specimen of #Spicomellus a few weeks ago, we were contacted by George Blasing, who said he'd bought some on the commercial market, and wanted to return it to Morocco. It arrived last week. Thanks George for doing the right thing in the name of science!

Photograph of the holotype and only known specimen of the hauffiopterygian leptonectid, Xiphodracon goldencapensis (ROM VP52596) from Golden Cap, between Charmouth and Seatown, Dorset, UK. The skeleton is exposed in ventrolateral view. The skull has been fully prepared free of matrix whereas most of the skeleton is still in matrix. The left (upper) forefin has been prepared so that it is
three-dimensionally preserved and projects upwards. Scale bar (lower left) is 20 cm.
