Ailuropodinae is a subfamily of Ursidae that contains only one extant species, the giant panda (Ailuropoda melanoleuca) of China.The fossil record of this group has shown that various species of pandas were more widespread across the Holarctic, with species found in places such as Europe, much of Asia, North America and even Africa.
Aptian extinction: 117 Ma: Unknown, but may be due to volcanism of the Rajmahal Traps [15] Jurassic: End-Jurassic (Tithonian) 145 Ma: No longer regarded as a major extinction but rather a series of lesser events due to bolide impacts, eruptions of flood basalts, climate change and disruptions to oceanic systems [16]
Giant panda eye. From Greek αἴλουρος aílouros "cat" + ‒ποδός ‒podós "foot" (gen. sg.). Unlike most bears, giant pandas do not have round pupils, but instead have vertical slits, similar to those of cats. This has not only inspired the scientific name, but in Chinese the giant panda is called "large bear cat" (大熊猫, dà ...
The most famous of these mass extinction events — when an asteroid slammed into Earth 66 million years ago, dooming the dinosaurs and many other species — is also the most recent. But ...
Extinction events can be tracked by several methods, including geological change, ecological impact, extinction vs. origination rates, and most commonly diversity loss among taxonomic units. Most early papers used families as the unit of taxonomy, based on compendiums of marine animal families by Sepkoski (1982, 1992).
Ling-Ling died suddenly from heart failure [2] on December 30, 1992, [3] at which time she was the longest-lived giant panda in captivity outside China. Hsing-Hsing would go on to pass her record when he was euthanized by zookeepers on November 28, 1999, at the age of 28 due to kidney failure . [ 4 ]

Population bottleneck followed by recovery or extinction. A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts; or human activities such as genocide, speciocide, widespread violence or intentional culling.
