Annie Alexander died #OTD in 1950. A pioneering amateur naturalist & paleontologist whose wealth and passion for science fueled her founding & financing two world-class scientific museums at UC Berkeley: Museum of Vertebrate Zoology (1908) & UC Museum of Paleontology (1921). #WomenInSTEM (1/2)

A black-and-white studio portrait of Annie Montague Alexander, an early 20th-century American philanthropist, explorer, and paleontologist. She is depicted in a three-quarter view facing slightly to the left, with short white hair, wearing round wire-framed glasses, a dark high-collared blouse or dress with a light collar, and a brooch pinned at the neck. Her expression is serious and composed against a plain, softly textured gradient background.A black-and-white photograph from an early 20th-century field expedition showing Annie Montague Alexander (center) standing outdoors in a rugged, rocky landscape with sparse vegetation. She has short white hair, wears a light-colored jacket, scarf, and practical outdoor attire, and smiles gently at the camera. To her left is another woman in a dark outfit and wide-brimmed hat holding papers; to her right, a third woman in a light hat and coat. The scene captures a moment of camaraderie during fieldwork, likely related to fossil collecting or natural history exploration.

A digital treasure trove of Quaternary #fossils from @ucmpberkeley.bsky.social now available! Efforts by PhD students from @liujuan.bsky.social's FAM Lab, UCMP's Pat Holroyd, and the small but mighty FAVE Lab CT made this open access resource possible: doi.org/10.1080/0272... @jvertpaleo.bsky.social

Happy #FossilFriday! 🐟New fish species described from Professor Juan Liu and Jiang-Yong Zhang! In their paper published in the Canadian Journal of Zoology, they describe Jianghanichthys huachongensis sp. nov., a fresh water cypriniform fish found in Guangdong, China. doi.org/10.1139/cjz-...

New fossil fish dropped! Meet Jianghanichthys huachongensis sp. nov. Despite fragile, swampy origins, exceptional preservation of its head sensory canals is shedding new light on Cypriniformes evolution! cdnsciencepub.com/doi/full/10.... #Paleontology #Ichthyology #Fossil #NewSpecies #Evolution

🌿Brand new research out in Science today about angiosperm reproductive strategies and how they preceded the K-Pg mass extinction, led by UCMP PhD student, Jaemin Lee, and curator, Cindy Looy!🌿 www.science.org/doi/10.1126/...

Diversification of angiosperm reproductive strategies predated the end-Cretaceous extinction

Angiosperm reproductive evolution is traditionally linked to the end-Cretaceous biotic crisis and subsequent ecological restructuring. Here, we report diverse and unexpectedly large diaspores (dispers...
