TLDR: Discovery of Paleoloxodon patticus, possibly the largest land mammal, challenges size records with its 18-19 ton weight, outclassing non-sauropod dinosaurs
This article is a summary of a You Tube video “The Elephant That Was Bigger Than Every Non-Sauropod Dinosaur Ever” by ExtinctZoo
Key Takeaways:
- Post-Dinosaur Mammalian Growth: After the extinction of non-avian dinosaurs, mammals began to grow larger, no longer limited by the presence of dinosaurs.
- Paraceratherium’s Size: The Paraceratherium, a hornless rhino from Eurasia 34 million years ago, was considered the largest land mammal until the discovery of a larger prehistoric elephant.
- Discovery of Paleoloxodon patticus: In the 1800s, a prehistoric elephant named Paleoloxodon patticus was discovered in India, challenging previous notions of the largest land mammal.
- Evolution of Paleoloxodon: The genus Paleoloxodon, to which P. patticus belongs, is believed to have evolved in Africa 4 million years ago, with P. rei being one of its largest species.
- Size of Paleoloxodon patticus: P. patticus was estimated to be around 14.3 feet tall at the shoulders and weigh 22 tons, making it larger than any non-sauropod dinosaur.
- Skepticism About Size Estimates: Some paleontologists are skeptical about the size estimates of P. patticus, believing the 22-ton figure might be an exaggeration due to fragmented remains.
- Revised Weight Estimates: A more complete specimen found in 2023 suggested a weight of 18-19 tons for P. patticus, still making it the largest known land mammal.
- Unique Physical Characteristics: P. patticus had a robust build, a uniquely shaped skull, and long tusks, aiding in its survival and feeding habits.
- Coexistence with Humans: Evidence suggests coexistence between humans and P. patticus, with some Paleoloxodon species showing signs of human hunting.
- Extinction and Legacy: P. patticus went extinct 40-50,000 years ago, likely due to climate change and habitat loss, with a possible contribution from human hunting.
