Galapagos tortoise species ID’d from specimen in UW museum
www.umsonst spiele de Kuje The skull and scutes of a newly-identified species of Galapagos giant tortoise in the UW-Madison Zoological Museum. The tortoise, which was hiding in plain sight on the Galapagos island of Santa Cruz, was identified by a group from Yale University. The UW-Madison specimen was acquired by the museum in 1991.

The specimen in the UW-Madison Zoological Museum is considered the « holotype » specimen, meaning it is the defining scientific example of the new animal species.
The specimen in the UW-Madison Zoological Museum, which was returned this past week by the Yale Peabody Museum of Natural History, is considered the « holotype » specimen, meaning it is the defining scientific example of the new animal species. The UW-Madison museum has only eight holotypes — including a subspecies of cougar from Wisconsin and some frogs from Papua New Guinea — in its collection of 500,000 animal specimens.
« Having a holotype is a big deal in the museum world, » explains Laura Monahan, the museum’s senior curator. « It is the single specimen representing a species to which subsequent finds need to be compared. »
Under the direction of former curator Elizabeth Pillaert, the museum has enjoyed a long partnership with the Ecuadorean National Park Service, which oversees the volcanic islands, famous for their large number of endemic species, including 12 extant species of giant tortoise.
The UW-Madison Zoological Museum currently houses one of the largest collections of materials from the Galapagos in North America. When dead animals are found, many are sent to UW-Madison, where they are prepared and curated, with most being returned to Ecuador and the remainder staying in Madison. Scientists from Wisconsin and around the world use the specimens in various scientific studies.
« I wish we had more of the tortoise, but this is what we have, » says Monahan as she peers into the box with the skull and scutes. Given that Galapagos tortoises can live to be 150 years old, the UW-Madison Zoological Museum’s claim to a holotype for an iconic animal of evolutionary biology may last for a while with few additional specimens to represent the rare animal.
