The terror birds, also known as phorusrhacids, were a group of large, carnivorous birds that dominated the South American landscape during the Cenozoic Era. These birds were characterized by their massive size, powerful beaks, and sharp talons, making them the apex predators of their time. However, despite their impressive reputation, the terror birds eventually went extinct, leaving behind a fascinating legacy of fossils and a lingering question: when did they go extinct?
Overview of the Terror Birds
The terror birds were a distinct group of birds that evolved during the Paleogene and Miocene Epochs, around 60-20 million years ago. They were characterized by their large size, with some species reaching heights of over 3 meters (10 feet) and weighing up to 100 kilograms (220 pounds). Their powerful beaks and sharp talons made them well-adapted to hunt and kill large prey, including mammals and other birds.
Extinction of the Terror Birds
The exact timing of the terror birds’ extinction is still a topic of debate among paleontologists. However, most researchers agree that they went extinct at the end of the Miocene Epoch, around 20-10 million years ago. This was likely due to a combination of factors, including climate change, the evolution of new predators, and the decline of their preferred prey species.
In this article, we will explore the history of the terror birds, their characteristics, and the circumstances surrounding their extinction. We will also examine the fossil record and the latest research on this fascinating group of birds.
When Did Terror Birds Go Extinct?
The terror birds, also known as phorusrhacids, were a group of large, carnivorous birds that dominated the landscapes of South America during the Cenozoic Era. These birds were characterized by their massive size, powerful legs, and sharp beaks. Despite their fearsome reputation, the terror birds went extinct at the end of the last Ice Age, around 10,000 to 12,000 years ago. In this article, we will explore the history of the terror birds, their evolution, and the reasons behind their extinction.
The Evolution of Terror Birds
The terror birds evolved from a group of small, bird-like creatures that lived during the Paleocene Epoch, around 60 million years ago. Over time, these early birds evolved into larger, more powerful species, with some species reaching heights of over 3 meters (10 feet) and weighing as much as 150 kilograms (330 pounds). The terror birds were characterized by their powerful legs, which were well-suited for running and hunting. They also had sharp, hooked beaks that were used to catch and eat their prey.

The terror birds were apex predators in their ecosystems, and played a crucial role in shaping the evolution of other species. They were likely responsible for the extinction of many other species, including large mammals and other birds. Despite their fearsome reputation, the terror birds were also preyed upon by other predators, including giant ground sloths and saber-toothed cats.
The Diversity of Terror Birds
There were several different species of terror birds that lived during the Cenozoic Era. Some of the most well-known species include:
- Phorusrhacos argentinus: This species was one of the largest terror birds, reaching heights of up to 3.5 meters (11.5 feet) and weighing as much as 200 kilograms (440 pounds). It lived during the Miocene Epoch, around 20 million years ago.
- Andalgalornis steulleti: This species was smaller than Phorusrhacos argentinus, reaching heights of up to 2.5 meters (8.2 feet) and weighing as much as 100 kilograms (220 pounds). It lived during the Pliocene Epoch, around 5 million years ago.
- Potamornis minimus: This species was one of the smallest terror birds, reaching heights of up to 1.5 meters (4.9 feet) and weighing as much as 50 kilograms (110 pounds). It lived during the Pleistocene Epoch, around 2 million years ago.
The Extinction of Terror Birds
The terror birds went extinct at the end of the last Ice Age, around 10,000 to 12,000 years ago. There are several theories about why the terror birds went extinct, including:
- Climate Change: The climate was changing rapidly during the late Pleistocene Epoch, with the Earth entering a period of warming. This may have made it difficult for the terror birds to adapt and survive.
- Competition with Other Predators: The terror birds were likely competing with other predators, such as giant ground sloths and saber-toothed cats, for food and resources. This competition may have made it difficult for the terror birds to survive.
- Loss of Habitat: The terror birds may have lost their habitat as a result of changes in the climate and the spread of human populations. This loss of habitat may have made it difficult for the terror birds to survive.
Conclusion
The terror birds were a group of large, carnivorous birds that dominated the landscapes of South America during the Cenozoic Era. They were characterized by their massive size, powerful legs, and sharp beaks. Despite their fearsome reputation, the terror birds went extinct at the end of the last Ice Age, around 10,000 to 12,000 years ago. The reasons for their extinction are still debated among scientists, but it is likely that a combination of factors, including climate change, competition with other predators, and loss of habitat, contributed to their demise.

When Did Terror Birds Go Extinct: FAQs
What were Terror Birds?
Terror Birds, also known as Phorusrhacids, were a group of large, carnivorous birds that lived during the Cenozoic Era, up to around 2 million years ago. They were characterized by their massive size, powerful legs, and sharp beaks.
Why are they called Terror Birds?
The name “Terror Birds” comes from their reputation as apex predators during their time. They were likely at the top of their food chain and preyed upon large animals, including mammals and other birds. Their size and ferocity would have made them a formidable force in their ecosystems.
When did Terror Birds go extinct?
The exact timing of Terror Bird extinction is still debated among scientists. However, it is believed that they went extinct around 2 million years ago, likely due to a combination of factors such as climate change, loss of habitat, and competition with other predators.

What was the largest Terror Bird species?
The largest Terror Bird species was Phorusrhacos argentinus, which is estimated to have stood around 3 meters (10 feet) tall and weighed around 150-200 kilograms (330-440 pounds). However, other species, such as Andalgalornis steulleti, may have been even larger.
Are there any modern birds related to Terror Birds?
Yes, Terror Birds are believed to be closely related to modern birds such as the Seriemas and the Tinamous. These birds are found in South America and share some physical characteristics with Terror Birds, such as powerful legs and sharp beaks. However, they are much smaller than their extinct relatives and do not possess the same level of ferocity and dominance.
