Somso Brain models of Vertebrates, C 1920.

“Brain Models of Vertebrates of Ziegler’s series based on the work of Prof. Dr. A. Wiedersheim” is a classic comparative zoology teaching set originally derived from the anatomical work of Robert Wiedersheim, a prominent German comparative anatomist known for his studies of vertebrate morphology. Dog (Canis familiaris) Rabbit (Oryctolagus cuniculus) Domestic pigeon (Columba livia domestica) American alligator (Alligator mississippiensis) Frog (Rana esculenta)Dog (Canis familiaris) Trout (Salmo trutta fario) Small-spotted catshark (Scyliorhinus canicula) River lamprey (Petromyzon/Lampetra fluviatilis) The model set contains enlarged brain models representing eight vertebrates arranged to illustrate evolutionary and comparative differences in brain structure:ach numbered brain is mounted separately on a stand and is not intended to be disassembled. The set reflects the comparative-anatomy tradition of the late 19th and early 20th centuries, when Wiedersheim’s work, especially his textbook Comparative Anatomy of Vertebrates, becaCanis familiaris)me a standard reference for understanding vertebrate evolution and morphology
