Dinofelis barlowi

Overview

Dinofelis barlowi is an extinct cat encountered through fossils from southern Africa. Although it belongs among saber-toothed cats, several features of its head and body evoke living cats such as leopards and lions. Finding similarities among different cats is part of its interest.^[1]

Key facts

The name barlowi also preserves a human trace. According to the Ditsong National Museum of Natural History, it honors Barlow, manager of the Sterkfontein quarry where the first specimen was found. Following a fossil’s name can reveal the story of a person who worked at the discovery site.^[3]

Time and place

Skull and body bones of this species were collected at Bolt’s Farm near Sterkfontein, South Africa. A 1991 study estimated the fossil-bearing deposits at approximately 2 million years old. Dating one discovery site offers an entry into southern Africa’s ancient animal world.^[2]

The time range describes source context, not the complete duration of this species.

Size, form and skeleton

Researchers compared postcranial bones as well as skulls and teeth. A 2001 study explains that Dinofelis barlowi shows especially strong similarities to living pantherine cats. This comparison reads head and body features together rather than focusing on one part.^[1]

A model based on dental data in the 2021 CarniFOSS study estimates a body mass of approximately 110 kg.^[4]

Habitat and reproduction

The Ditsong museum’s comparative account pictures its setting as forests, forest margins, and wooded grasslands. Imagine a landscape linking dense vegetation with open areas. This is a research story inferring possible habitat use from fossil body form.^[3]

Fossil discovery

Material collected at Bolt’s Farm by the University of California African Expedition in 1947–1948 included a Dinofelis barlowi skull and postcranial bones. Baboon skulls and skeletons were also found, and Cooke suggested that animals may have accumulated after falling into a natural trap. Finding why bones gathered together is an important excavation question.^[2]

Research questions

Why might distantly related cats look similar? A 2001 study discussed convergence of Dinofelis body features toward those of living pantherines. Species within Dinofelis did not all change in the same direction, providing an intriguing reason to compare head and body features separately for each species.^[1]

Observation

Follow the cat-like outline from the head through the neck into the trunk. Alongside this overall impression, fossil research compares skull, dental, and postcranial features separately. Observation can begin by finding the parts that remind you of a familiar cat.^[1]
