🐎Bron, also known as Thunder beasts, were massive mammals that lived around 38 million years ago.
🔄Bron experienced a rapid size increase over a mere 20 million years, evolving from small dog-sized species to rhinoceros to elephant-sized creatures.
🌍Bron species diversified into larger and smaller new species over time, and ecological conditions played a role in the net increase in body size.
⚖️Bigger body sizes can provide advantages in defense, predation, mate competition, and intelligence. However, smaller lineages may have their own benefits in crowded niches.
🌬️Environmental changes and competition likely led to the extinction of Bron and other giant animals around 34 million years ago.
