Remarkable Fossil Unearthed: The Prehistoric 265-Million-Year-Old Dominant Predator of Brazil Before the Age of Dinosaurs
Before dinosaurs assumed their eminent role in natural history, Pampaphoneus biccai dominated as the foremost predator in South America, around 265 million years ago. A newly discovered, well-preserved fossil originating from Brazil grants further understanding into this prehistoric leviathan.
Long before dinosaurs gained their iconic status as the colossal and fearsome predators, Pampaphoneus biccai had already secured its place as South America’s reigning apex predator, some 40 million years prior. It was the era’s most intimidating carnivorous creature.
Recent scholarly work published in the Zoological Journal of the Linnean Society unveils this momentous finding. An international research team has uncovered a fossil of Pampaphoneus biccai that is remarkably well-preserved. This 265-million-year-old specimen was discovered in the rural vicinity of São Gabriel in Southern Brazil.
This extraordinary fossil consists of a full skull along with various skeletal elements like ribs and limb bones. Pampaphoneus belongs to the early therapsid group known as dinocephalians, which existed shortly before the Earth’s most devastating extinction event that eradicated nearly 86% of all animal species globally.
Prior to this cataclysmic event, dinocephalians were among the primary categories of large land-dwelling creatures. These animals varied in size and dietary habits, including both herbivorous and carnivorous types. Named for their thick cranial structures, “dinocephalians” translates to “terrible head” in Greek. While relatively common in regions like South Africa and Russia, this category of creatures is scarce in other global regions. In Brazil, Pampaphoneus biccai stands as the only identified species.
The principal author of the study, Mateus A. Costa Santos, a graduate student at the Federal University of Pampa (UNIPAMPA), remarked on the rarity of the finding. According to Santos, the discovery of a new Pampaphoneus skull was vital for enriching existing knowledge of this species, which had been previously hard to distinguish from its Russian counterparts.
Researchers from UNIPAMPA and Universidade Federal do Rio Grande do Sul (UFRGS) acquired the fossil after a month of rigorous fieldwork. The Covid-19 pandemic delayed the subsequent cleaning and comprehensive analysis of the fossil for an additional three years. Professor Stephanie E. Pierce collaborated in the investigation, contributing to the ongoing research led by senior author Professor Felipe Pinheiro, UNIPAMPA, on Brazil’s Permo-Triassic fossil record.
Pierce described the animal as fearsome and emphasized its significance for understanding terrestrial ecosystems right before the largest mass extinction event in Earth’s history. The fossil record of Brazil, she noted, holds global significance.
This new specimen constitutes only the second known Pampaphoneus skull discovered in South America. It surpasses the first in size and provides invaluable data about its morphology owing to the extraordinary preservation of its skeletal elements.
According to Pinheiro, Pampaphoneus occupied an ecological niche similar to modern-day large felines. As the largest known terrestrial predator of its time in South America, it possessed large canine teeth adapted for capturing prey. Its strong dentition and skull structure suggest that it was capable of bone-crushing, similar to contemporary hyenas.
While the newly found skull measures nearly 40 cm, other research indicates the possible existence of a Pampaphoneus individual up to twice as large. This third specimen is known only by a fragment of its jaw but exhibits sufficient characteristics for identification.
Researchers estimate the most enormous Pampaphoneus individuals could reach almost three meters in length and weigh around 400 kg. This apex predator was adept at hunting small to medium-sized animals, and fossils of potential prey have also been unearthed in the same locale, including the diminutive dicynodont Rastodon and the immense amphibian Konzhukovia.
The newly discovered Pampaphoneus specimen, along with other fossilized animals from the region, attests to the significant paleontological promise of Brazil’s Pampa region.
This scholarly investigation was supported by various funding bodies including the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior-Brasil (CAPES), the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), and the Harvard Lemann Brazil Research Fund.

Never thought Brazil had such significant fossils. this changes everything in my view of prehistoric life there.
These fossils tell us so much about earth’s history. Just incredible. We need to preserve these finds for future generations to learn from.
who funded this? Always curious about where the money comes from for these big discoveries.
Thats some real Jurassic Park stuff there. But 265 million years old? that’s crazy!
Wow, this is insane. A predator before the dinos? Makes you think what else is buried out there waiting to be found.
This is a game changer in paleontology. Imagine the tech we’ll have in a few years to uncover even more.
Always astounded by these findings. Hats off to the researchers for their hard work. It must’ve been a painstaking process.
i’m intrigued by how this fits into the larger extinction event. Makes u think how fragile life really is.
