We need to be more honest about the nature of the job market with students, and one way of doing that is by showing them the data. Turns out, we also need better data collection on (at least US) paleo careers www.cambridge.org/core/journal...

Every field needs this kind of info so students—esp first gen PhD’ers—can go in knowing what’s up.

Might it depress applications? Yes. Might applicants be less diverse? Yep. But until those already in power fix the system, ppl need to know how bad it is.

We recently published a paper on the grim trends in US paleo employment. What we also realized is that we don’t have very good data on where IS paleo PhDs end up and how many end up leaving the field. We need to start collecting better data! www.cambridge.org/core/journal...

"We found no evidence of migratory behavior in species that exhibit this behavior today. Ancient foragers likely hunted prey that were available year-round, consistent with zooarchaeological and genetic evidence for reduced mobility at the end of the Pleistocene." 🏺🧪🦣

BEHOLD the GARgantuan Alligator Gar!!!

This is the largest Alligator Gar I’ve encountered; at over 7 feet 10 inches (240 cm) and approximately 55 inches in girth, its weight is estimated at 300 pounds (136 kg)!

A true river monster, among the largest caught, tagged and safely released! #GarWeek

A giant Alligator Gar (fish) lies in a boat, captured for research and safely released after measurements and tagging.

Illustration from 1896 showing detailed views of the skull of a Torosaurus, a large ceratopsid dinosaur from the Cretaceous period. The top section depicts the broad, heart-shaped frill with two large oval openings. Below is a partial front view of the skull bone structure, including the elongated curved horns on each side and the pointed beak-like snout. The illustration includes labels and dotted outlines indicating missing parts, emphasizing the distinctive features of the Torosaurus's cranial anatomy.

L is for... Lithograph! A lithograph is a stone with an image drawn out in a greasy material, and the surrounding stone is etched out to create a water-receptive surface. The ink will only adhere to the drawing, allowing for printing of an image, as shown here in Breaking Ground.

Illustration of a Siberian ibex (Capra sibirica sacin) standing on rocky terrain with faint mountain outlines in the background. The ibex has a light brown to beige coat with darker shading on its face and legs. Its most notable feature is the large, curved, ridged horns that sweep backward in an arch above its head. The animal has a short black beard under its chin and a dark tufted tail. The ibex stands with one front leg raised, highlighting its muscular build and sure-footedness, characteristic of mountain-dwelling goats. The drawing is detailed and colored, with fine shading emphasizing texture and form.

Historical black-and-white illustration titled "Mastodon productus" from an 1877 report, depicting detailed fossilized teeth and bone fragments of a mastodon discovered in New Mexico during the 1874 expedition. The image includes various views of molars with distinct cusps and ridges, jaw fragments, isolated teeth, and a sectioned tusk or bone, all rendered with fine stippling and shading to highlight texture and form. Each fossil element is numbered for reference, arranged neatly on a plain background, showcasing the extinct vertebrate's dental and skeletal anatomy for scientific study.
