Terminator Pigs Diet: Study Reveals
- Fossilized teeth reveal insights into the diet of entelodonts, nicknamed "terminator Pigs," that roamed Eurasia and North America between 20 and 40 million years ago.
- Entelodontidae, a family of mammals existing roughly 35 to 20 million years ago, were distantly related to modern pigs but more closely linked to hippos and cetaceans.
- Researchers have long been curious about the behavior and eating habits of both entelodonts and anthracotheres, an extinct family of ruminants resembling hippos but more agile.

Fossilized teeth reveal insights into the diet of entelodonts, nicknamed “terminator Pigs,” that roamed Eurasia and North America between 20 and 40 million years ago. A study published in Palaeogeography, Palaeoclimatology, Palaeoecology sheds light on the feeding habits of these extinct mammals.
Entelodonts: Not-So-Picky Eaters
Entelodontidae, a family of mammals existing roughly 35 to 20 million years ago, were distantly related to modern pigs but more closely linked to hippos and cetaceans. Popularly known as “Hell Pigs” or “Terminator Pigs,” these creatures possessed formidable jaws, prompting questions about their dietary preferences.
Researchers have long been curious about the behavior and eating habits of both entelodonts and anthracotheres, an extinct family of ruminants resembling hippos but more agile. Both groups exhibited unique morphological characteristics,making their ecological roles somewhat enigmatic.

Dental Clues to Dietary Habits
Researchers from the Catalan Institute for Human Paleoecology and Social Evolution analyzed fossilized teeth from specimens found in southern France, dating back approximately 30 million years to the Oligocene epoch.
Microscopic wear patterns on teeth provide valuable details about an animal’s diet. Such as, consuming bones and seeds tends to create pits, while grazing on grasses and foliage leaves behind scratches. These micro-wear patterns, invisible to the naked eye, offer clues to what these animals ate.
The team compared these micro-wear patterns with those of modern mammals with known diets, including wild boars, bears, lions, hippos, and horses. The analysis suggested that anthracotheres primarily consumed plant matter. the micro-wear on their teeth resembled that of grazing and fruit-eating mammals.
In contrast, the diet of entelodonts appeared similar to that of wild boars and modern peccaries. These findings suggest that entelodonts were not strictly carnivorous. However, like modern pigs, they may have opportunistically consumed meat when available.
Adaptable Diet for a Changing World
The study’s results indicate that both entelodonts and anthracotheres inhabited a diverse ecosystem with access to various food sources. During their time, the Earth transitioned from the warm, humid conditions of the Eocene epoch to the cooler climate of the Oligocene. A flexible diet likely aided these animals in surviving this environmental shift.
Ancient ‘Terminator Pigs’ and Their Diet: A Q&A
What were “Terminator Pigs”?
“Terminator Pigs,” also known as entelodonts, were a family of extinct mammals that roamed eurasia and North America between 20 and 40 million years ago. They are scientifically known as Entelodontidae.They earned their nickname due to their formidable jaws and were distantly related to modern pigs, but were more closely related to hippos and cetaceans. This facts comes from a study published in Palaeogeography,Palaeoclimatology,Palaeoecology.
What did “Terminator Pigs” look like?
Unfortunately,the provided text does not describe the physical appearance beyond the mention of their ”formidable jaws.” However, the text mentions that they are distantly related to modern pigs and were also referred to as “Hell Pigs.” The included image shows a skull of Archaeotherium mortoni, an entelodont from North America, but doesn’t give a complete picture of what they looked like in life.
What did “Terminator Pigs” eat?
A recent study using fossilized teeth suggests that “Terminator Pigs” had a varied diet. They weren’t strictly carnivorous, but their diet likely resembled that of modern wild boars and peccaries. This means they may have eaten a combination of plants and meat, perhaps scavenging or consuming meat when available.
How do scientists determine what extinct animals ate?
Scientists can analyze the microscopic wear patterns on fossilized teeth to determine an animal’s diet. Different types of food leave different marks. For example:
pits: Usually suggest the consumption of hard foods like bones or seeds.
Scratches: Indicate a diet of softer foods such as grasses and foliage.
Researchers compare these wear patterns to those of modern mammals with known diets to make inferences about what extinct animals ate.
what other animals were studied alongside “Terminator Pigs”?
Researchers also studied anthracotheres, an extinct family of ruminants that resembled hippos. They wanted to understand the eating habits of both groups, despite their different ecological roles.
What did the study reveal about the diet of anthracotheres?
The analysis of anthracothere teeth revealed that they primarily consumed plant matter. Their micro-wear patterns resembled that of grazing and fruit-eating mammals, indicating a herbivorous diet.
Where were the “Terminator Pig” teeth found for this study?
Researchers from the Catalan Institute for Human Paleoecology and Social Evolution analyzed fossilized teeth from entelodont specimens found in southern France. These fossils date back approximately 30 million years, to the Oligocene epoch.
How did the diet of entelodonts help them survive?
The study indicates that a flexible diet likely helped both entelodonts and anthracotheres survive environmental changes. The Earth was undergoing a transition from the warmer, humid conditions of the Eocene epoch to the cooler climate of the Oligocene period, where the availability of specific food sources might have fluctuated.
Summary of Dietary Findings
Here’s a comparison of the dietary habits of entelodonts and anthracotheres based on the study:
| Feature | Entelodonts (“Terminator Pigs”) | Anthracotheres |
| —————– | —————————————– | —————————— |
| Diet Type | Omnivorous (potentially opportunistic) | Herbivorous |
| Dietary Clues | Teeth wear similar to wild boars | teeth wear similar to grazing mammals |
| Food Sources | Variety of both plants and meat. | Primarily Plant Matter |
