With my upcoming departure from the University of Michigan, I've found myself deep in the job hunt process. Moving back to Canada from the U.S is certainly something I'm really looking forward too. If any 🇨🇦 labs (especially in Alberta) are searching for a µ-CT expert, please let me know!

New in @science.org ...since our first discoveries of early tetrapods, they have been thought of as "amphibians" characterized by aquatic larvae. But is this true? For the first time, we report exceptional fossils of stem tetrapod babies that upend this paradigm. 1/n www.science.org/doi/10.1126/...

Direct development of stem tetrapods across the fin-to-limb transition

Modern amphibians are characterized by an aquatic larval stage that ends abruptly with a period of widespread tissue remodeling (metamorphosis) upon transition to terrestrial adulthood. A transient la...

After 7.5 years, I'm leaving my role as the UMMZ µ-CT lab manager at the end of July. This has been the most productive, and fulfilling period in my scientific career so far. I'm proud to say I've trained over 20 students, contributed to several publications, and generated over 12,000 µCT datasets.

Corresponding text is "show me the best sail-backed tetrapod" (Spinosaurus), "I said the best sail-backed tetrapod" (Dimetrodon), and "perfection" (Platyhystrix)

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

#Education resource! Over the years I created this collection of colored skull #3Dmodels for teaching. They're available to download on MorphoSource & to view on Sketchfab. Because of recent changes to Sketchfab, I migrated them to my website: www.graysvertebrateanatomy.com/work/colorso... (1/3)
