Thylacinids (say: Thy-la-SIN-ids) were a group of meat-eating marsupials. They belonged to a family called Thylacinidae. These animals lived a long time ago, from about 33 million years ago until very recently. The most famous thylacinid was the Thylacine, also known as the Tasmanian Tiger. Sadly, all thylacinids are now extinct, meaning they no longer exist on Earth.

What are Thylacinids?
Thylacinids were a family of mammals that carried their babies in a pouch. This makes them marsupials, like kangaroos and koalas. They were all carnivorous, meaning they ate meat. They were part of a larger group of marsupials called Dasyuromorphia, which also includes animals like quolls and Tasmanian devils.
Where Did They Live?
Most thylacinids lived in Australia. Some also lived in New Guinea. They roamed these lands for millions of years. Their fossils have been found in different parts of Australia.
When Did They Live?
The oldest thylacinid fossils are from the Early Oligocene epoch. This was about 33 million years ago! The last known thylacinid, the Thylacine, died in 1936. This means they lived for a very long time on Earth.
Different Types of Thylacinids
Scientists have found fossils of many different kinds of thylacinids. While the Thylacine is the most well-known, it was just one of many species. These different types are called genera and species.
The Famous Thylacine
The Thylacine (Thylacinus cynocephalus) was the largest known carnivorous marsupial. It looked a bit like a dog with stripes on its back, which is why it was called the Tasmanian Tiger. It lived in Tasmania until the 1930s.
Other Ancient Thylacinids
Many other thylacinid species lived long before the Thylacine. For example, there were species like Badjcinus turnbulli and Nimbacinus dicksoni. These ancient relatives help us understand how thylacinids changed over millions of years. They varied in size and might have lived in different habitats.
Why Did They Disappear?
All thylacinids are now extinct. The reasons for their disappearance are complex.
Habitat Loss
Over time, the places where thylacinids lived changed. Forests were cleared, and their hunting grounds became smaller. This made it harder for them to find food and survive.
Competition with Other Animals
When humans arrived in Australia, they brought new animals, like dingoes. Dingoes were also meat-eaters and competed with thylacinids for food. This competition might have made it harder for thylacinids to thrive.
Human Impact
For the Thylacine, hunting by humans played a big role in its extinction. People believed thylacines hunted sheep, so they were hunted down. The last known Thylacine died in a zoo in 1936.
