19th Century - Artensterben

The extinct quagga was about 257 centimeters long and reached a shoulder height of 125 to 135 centimeters. Unlike other zebras, its brown and white stripes were located on the front part of its body, while the rear part of the body was unstriped. (© Nicolas Marechal, Public domain, via Wikimedia Commons)

Quagga

Half zebra, half horse The British naturalist William Burchell is often regarded as the discoverer of the animal that travelers described as “half zebra, half horse” or “unfinished zebra“—the quagga. However, the species had already been mentioned earlier by explorers. Even before Burchell’s “discovery” in 1812, the English naturalist George

Study Questions the Myth of the Extinct Cape Lion as a Distinct Subspecies

A study published yesterday in Scientific Reports questions the taxonomic status of the Cape lion (Panthera leo melanochaita), which was driven to extinction around 1860. For a long time, this large cat was considered a distinct subspecies, characterized by its striking black mane that extended over its shoulders and belly,

Extinctions: How Many Animal Species Have We Already Wiped Out?

There have been five mass extinction events in the history of Earth’s biodiversity, all caused by natural phenomena. It is believed that the sixth mass extinction is currently underway, this time solely driven by human activities. The Thylacine, the aurochs, and the dodo are just a few of the most

The Tonga ground skink is known from only two specimens collected on Tongatapu in the early 19th century. The species reached a snout–vent length of almost 18 centimeters, plus tail.

Tongan Ground Skink

From the South Pacific to the museum—the last Tongan ground skinks The Tongan ground skink, a giant lizard, is known only from two specimens that are now housed in the Natural History Museum of Paris. The French doctors and naturalists Jean-René-Constant Quoy and Joseph Paul Gaimard collected the two animals

Himalayan Quail

A mysterious bird The Himalayan quail is one of the mysteries of avian fauna. It was last conclusively sighted, in 1876, and all subsequent search expeditions were unsuccessful. Nevertheless, many scientists believe it could have survived to this day. The IUCN still lists the bird from the pheasant family (Phasianidae)

Delcourt’s Giant Gecko

The largest gecko in the world … In the early 1980s, French museum employee Alain Delcourt discovered a forgotten specimen of a single stuffed giant gecko in the basement of the Natural History Museum of Marseille, which had previously been on public display for years. This species was previously unknown

Ula-ai-hawane

The Hawaiian island chain once harbored 57 species of honeycreepers Honeycreepers (Drepanidini), a tribe within the finch family (Fringillidae), occur only on the Hawaiian island chain. As a sister group, the honeycreepers are closely related to the rosefinches (Carpodacus), yet many species have developed traits that differ from those of

Jamaican giant galliwasp

Last seen in 1851 The Jamaican giant galliwasp, endemic exclusively to the Caribbean island of Jamaica, belongs to the family of diploglossids (Diploglossidae)—lizards with small but well-developed legs. A report written around 1850 by the English naturalist Philip H. Gosse indicates that the Jamaican giant galliwasp was still commonly found
