Regarding potential virtual paleontology meetings. (I built and ran the 2023 SVP virtual meeting.)
If there’s a desire for an online-based robust virtual paleontology “meeting”, my honest best advice is the folks that really really want this to happen aggregate a leadership team and make it happen. This isn’t a dig (🥁) at all, but it’s not going to happen through SVP this year. I ran the 2023 virtual meeting and promise there just isn’t enough time on the calendar to go the SVP route. 

If a team of 8-12 highly motivated, reliable individuals can be brought together on this and establish 10-point lists of benefits, challenges, and deliverable targets, I will enthusiastically help however I can in a consulting capacity. Please understand though that however much work you think this will be, double that and you might be close. Not trying to discourage anyone, but that’s the reality of these things. That said, accessibility is crucial and this overall concept is definitely worth pursuing.

It’s tangential to his relationship with Epstein, but remember Jack Horner rose to fame by claim jumping Marion Brandvold. She found Egg Mountain and the baby Maiasaura, loaned them to Jack, and had to sue to get them back - returned in 2004.

A rare view of the charming, crooked smile of Black Beauty's original skull at the Tyrrell Museum. #FossilFriday
Picture of the front of a Tyrannosaur rex skull. Specifically, the skull of the Black Beauty specimen at the Royal Tyrrell Museum, named so because the fossils have a unique black colour. The skull is held up by steel bars. The left side of the skull (right side of the photo) is more flat than the other side due to the fossil being compressed in one direction after burial. This makes the skull have a bit of a crooked smile.

Gotta say this whole sand thing is pretty funny. One thing Plait was adamant on is he thinks lay folks don't define sand as a size category. But they do! Regular people will tell you if a beach is sandy or gravely, because they see and feel the different grain size.

Proud to announce two models I painted went on display at the Manitoba Museum for their "Weird Wonders" from the dawn of complex life display! I got to paint Stanleycaris and Cambroraster. Sadly forgot to take close ups of the finished models, so the close ups are WIPs. Go see them at the museum!
Museum display showing a model of the Cambria marine arthropod Stanleycaris to the left of the original fossil. The fossil is in a slab of flat tan mudstone. The model is sandy coloured with large sphere shaped black eyes and two strange clawed mouth parts. The display is set up on terraced pale coliured plywood. 

The exhibit text reads as follows:
Stanleycaris hirpex had a third eye in the middle of its head. Similar to modern dragonflies, this extra eye may have helped it to stay oriented while swimming fast, while the pair of stalked, multi-faceted eyes provided a more detailed view of the surroundings. ROMIP 68665. 3D model artists: Sabrina Cappelli/Mira Thompson.Stanleycaris model. The colour of it is sandy tans and browns. Dark coloured splotches run the length of the body, which is flanked by a dozen or so fin like appendages. Its face has one black sphere shaped eye on an eyeshadow and another oval shaped one at the front centre of the head. Underneath the head are curled and clawed mouth parts. Display showing a fossil and model of the Cambrian marine arthropod Cambroraster on the right and left respectively. The fossil is in a square grey slab of shale and is of the "millennium falcon" shaped carapace. The model is about 1/3 the size of the fossil, is tan coloured and the carapce is covered in a lattice/fish net like pattern of dark cracks.

The exhibit text reads as follows:
Cambroraster falcatus had a tiny body and a shell covering its head which resembled the Millenium Falcon spaceship from Star Wars, inspiring its name. This enabled it to plough through the mud in search of buried prey. ROMIP 66030. 3D model artists: Lars Fields/Mira Thompson.WIP picture of Cambroraster falcatus model. The model is overall a tan to yellow colour. The prominent carapace is featured near the camera and is covered in a dark brown lattice of cracks. Its two eyes are black and rice grain shaped, sitting atop eye stalks at the back of the carapace. The "fins" on the sides of the body behind the carapace are subtly covered in brown, vein like patterns.
