Yes, the procoptodon goliath had predators. The Varanus priscus (a very large lizard) and the Thylacoleo, better known as the marsupial lion, were predators of the procoptodon goliath.

The procoptodon goliah, a giant kangaroo species, likely became extinct due to a combination of climate change, human hunting, and competition with other mammals for resources. These factors put significant pressure on their population, ultimately leading to their extinction.

There was once a giant kangaroo, now known as the Procoptodon. It was one of the many species known as Australian megafauna, and became extinct thousands of years ago. The giant kangaroo no longer exists.

The procoptodon, or procoptodon goliah, was the Giant Short-faced Kangaroo which lived in Australia thousands of years ago. Fossils have been found in all of the mainland states (therefore, not Tasmania), but not conclusively yet in the Northern Territory. Evidence of this giant marsupial has been found in the Darling Downs in Queensland; around the far-fling regions of Tocumwal, Bingara and Lake Menindee in New South Wales; the Eyre Peninsula and Naracoorte Caves in South Australia; and the Nullarbor Plain cave deposits of Western Australia.

Animals such as PROCOPTODON,DIPROTODON,TOXODON,MAMMUTHUS,DEINOTHERIUM,COELODONTA lived in the quaternary period.Plants such as BIRCH,SWEETGUM lived in the quaternary period, as well as the plants and animals you see around you.

Protoceratops lived in what is now Mongolia during the Late Cretaceous period, around 75 million years ago. They inhabited semi-arid environments with sand dunes and sparse vegetation.

Kangaroos and rabbits are not related even remotely. They share no common ancestor. The kangaroo's ancestor was a much larger version of the modern kangaroo, and quite unlike any ancestor of the rabbit.

Dinosaurs lived in the Mesozoic Era. This was a time between 230 million and 65 million years ago. The Mesozoic Era is divided into three time periods: the Triassic, Jurassic and Cretaceous periods.

prehistoric creatures is a term given to any kingdom which lived before the evolution of man. most commonally associated with extinct kingdoms. but many prehistoric creatures have either died out or have evolved into the peak of its existence.

e.g tyrannosaurs Rex. or crocodilian.

to many to specify.

Animals that lived and died before writing (not drawing) was devloped to create a recorded written history of the animals. All we have are archeological findings such as fossils and cave drawings to decipher the animals time and place on earth

The animal most people recognise as the kangaroo is common and not at all endangered. These animals, the Red Kangaroo and the two varieties of Grey Kangaroo, which are the largest of the marsupials, enjoy healthy populations throughout their particular habitats.

However, there are many smaller species of kangaroo, which are kangaroos in name only, and not in stature, appearance or even diet. Some of these smaller endangered kangaroos, most of which are actually wallabies, include the quokka, bettong, potoroo, tree-kangaroo, rufous-rat kangaroo (not to be confused with kangaroo rats), most species of rock wallaby and other wallabies such as the bridle nailtail wallaby. As for the reasons for their endangerment, in most cases it is the introduction of non-native predators such as foxes, feral cats and wild dogs which pose the biggest threat.

Not all kangaroos are endangered: you can search the IUCN Redlist for endangered kangaroos at the related link below.
