Darwin's Fossil Sand Dollar at Harvard

 


After watching more videos from the The Society for the Preservation of Natural History Collections (SPNHC) YouTube channel. I found another interesting one to highlight. It was created 2019 for the Specimen Spotlight Wednesday presentation May 25-31 meeting. The presenter was Jessica D. Cundiff of the Museum of Comparative Zoology (MCZ) of Harvard University, Cambridge, Massachusetts, USA.

Echinarachnius juliensis (Desor, 1847) was collected in Port St. Julien, Patagonia, Argentina during the HMS Beagle voyage (1831-1836) by Charles Darwin in 1834. Darwin sent the echinoid to Swiss biologist Louis Agassiz who also started the MCZ in 1859..  Described by Pierre Jean Édouard Desor in France Geological Society Bulletin vol. 4, number 2, pp. 287-288 in 1847. It appears this fossil is from the Neogene Period (aka Late Tertiary).
