A page from the ebook version of "A Visual Atlas of Skeletal Growth and Development" by Kyra Stull and Heather Garvin. This page features an image of acetabular development from newborn to 17.5 years. Each of the 19 acetabulae shown are yellow 3D models based on CT scans and oriented in lateral views such that the image focuses on the acetabulum. The upper part of the ilium is cropped out in hipbones after the age of 1.5 years. The age labels and title of the image ("Acetabular Development") are light blue boxes with black text. The bottom of the page has the caption "Figure 4.1 Acetabular development, newborn to 17.5 yoa. Lateral views presented at each designated age."

#NewBook alert: A Visual Atlas of Skeletal Growth and Development by Kyra Stull & Heather Garvin. Just look at the number of ages in this image!

An anole extends its dewlap, which says "call for scientists!"

Seeking scientist volunteers for this fall! Want to practice science communication and help author a 🌟comic🌟 about your research? I need collaborators for the next cohort of SciComm & Comics art and design students. All countries and scientific fields eligible.

PhD-level, y'all.

A terrible diagram of the skull courtesy of ChatGPT.

The skull according to ChatGPT: Mandible mandible mandible!

Yesterday I discovered that ChatGPT's PhD-level expertise didn't extend to bird anatomy. This morning I thought, perhaps I was being too hard on the half-trillion-dollar company. Birds are a little weird, anatomically speaking. Let's try something more familiar. A mammal. Behold.

Grade F level diagram of an ostrich skeleton. The pelvis is labelled as a humerus, and sternum appears to be labeled as the pelvis.

The team of Ph.D. level experts in ChatGPT apparently doesn't include any anatomists.

Testing the movement for the Shark Cranial Kinesis model. Think this is pretty close?

Shark/marine/anatomy people, I'd love your feedback! Intended for outreach for "general public". In the final version the parts will each be a different color.

Image of a 3D model of a veiled chameleon skull, with bones colored to demonstrate skull anatomy, on a black background. Model is shown in lateral (top), antero-lateral (middle), and anterior (bottom) views. A small image of the whole museum specimen is shown with a scale bar in the bottom right corner.

Climbing into my #ColorsOfSkullAnatomy collection: a veiled chameleon (Chamaeleo calyptratus) 🦎 this large male was getting up there in age when he was collected, as shown by his worn down teeth and bone pathologies.

PG-18: turtles reach adult shell shapes at about 65% maximum carapace length - Swiss Journal of Palaeontology Ontogenetic shell shape changes of turtles are often only documented for individual species. It is currently unclear how shell shape changes during ontogeny across species, if there are common trends,...

New paper by Guilherme Hermanson & me out: we explore ontogenetic shell shape change in turtles to check if there is a size threshold at which turtles reach adult shapes. This started for a different (in prep) study & was a fun little project w preliminary data

Messy start

With many postdoc grants like the NSF PRFB, Ford Fellowship, and Hanna H. Gray fellowships disappearing, I am currently looking for grants that could fund incoming postdoctoral scholars. Here is a thread of some of them 🧵

After 11 months in review, grateful to learn that my NSF proposal examining the ecomorphology and evolution of mammalian skull dimorphism was awarded!

Stay tuned for research on intraspecific effects on maroevolution and more undergrad-led projects! @uwbiology.bsky.social

I need to remember this the next time my scans won’t align or a landmark won’t register. As much as troubleshooting tech can be annoying, at least I’m not collecting 3D data from physically suspended bones!
