Verzameling gefossiliseerde armpotigen, Spirifer before 1894

This 19th-century illustration depicts a collection of fossilized brachiopods, a type of marine animal with a hinged shell. The detailed drawings, likely created for a scientific publication, showcase various species of Spirifer brachiopods, including Spirifer trigonal, Spirifer subcuspidatus, and Spirifer bischoffi. These detailed illustrations, likely from the Royal Museum of Brussels, provide valuable insight into the morphology and diversity of these extinct creatures.
