two Tusciziphius are illuminated by an artificial light during the night, one has albinism while the other is a more normal looking colouration
Tusciziphius is an extinct species of basal beaked whale that inhabited various parts of Europe and North America throughout the Miocene and Pliocene. both species are only known from skulls, but the skulls provide a unique morphology in the presence of a raised "keel" on their fused premaxillary bones. this may have been an attachment point for a large melon or used for something else, we still arent sure
a Cyrtograptus floats suspended amongst other plankton. the small colonial organism floats along the current, each of the small zooid's tentacles catching bits of ditritus and other plankton that happen to float by
Cyrtograptus is a kind of planktonic marine invertebrate that may seem closer related to cnidarians like siphonophores, but is actually closer related to us and echinoderms as it's a hemichordate. this genus is characterised by its spiral coiling with primary and secondary branches of zooids growing from the outer edge of the whorl
a Callawayia has just surfaced to take a breath, it quickly darts back underwater as to not be ambushed from below
Callawayia is an ichthyosaur from Canada with a proportionally longer tail than other icthyosaurs, ichthyosaurs were a group of very successful fully marine reptiles that appeared similar to cetaceans however they swam side to side rather than up and down
during sunrise, a spooked Doryaspis kicks up sand with its tail and cornual plates. it shoots jets of water out of its branchial openings from the force of sucking in water to breathe as it makes its escape
Doryaspis is a kind of jawless fish that inhabited the Devonian of Norway, it is well known for its heavily armoured body, long cornual plates that look like wide pectoral fins, and long pseudorostrum. while the use of its pseudorostrum are heavily debated, biomechanical studies of the fish show that it wouldve swam the most efficiently close to the bottom of the water.

ICE agents reveal daily arrest quotas and surveillance app in rare court testimony
Under oath, officers said they were told to make eight arrests a day and given special tech to help choose βtargetsβ
When a federal judge (finally) put ICE officers under oath, they admitted that they are given daily detention quotas and rely heavily on a Palantir-supplied AI tool to select targets, without warrants and without enough evidence to obtain one. They simply go into neighborhoods and round people up.

We Need To Stop With The "Women Didn't Work" Myth
YouTube video by Karolina Ε»ebrowska
This woman is a QUEEN. But also, did you know. A lot of Natural History scientific illustrators in the 19th century, were usually partners and wives of famous male academics. Buckland, Lyell, Mantell, Murchinson, Gould etc. Their academic output was carried by their (invisible) wives.

Long-necked theropod dinosaur model with scruffy grey feathers on its body. In a case with a worn-out label that identifies it as Syntarsus.
opposite side, which has exposed skeleton. There's some variation in color and texture of the bones, but I imagine they're all casts.
A "Syntarsus" half mount at the National Museum of Zimbabwe (via my colleague who always gets to travel to cool places). Interesting that it has both feathers and a dragging tail.

Okay, not really a fan of the whole "the plants change, the animals starve" thing. Although the image of the Stegosaurus skeleton overgrown with flowering plants is damn epic in a tragic way.

Hey fellow scientists, I'm just letting you know that if you're promoting something with some junky AI image, I'm not gonna click. You've got a workshop, a conference, a new paper?
Just not gonna bother. You want a bespoke image? Hire an illustrator.
