Arthur’s Field Note: The river rogue of the sea—the Bull Shark is equal parts brawler and explorer. Few sharks can match its adaptability, thriving where salt meets fresh and current meets chaos.
Details: • Species: Bull Shark (Carcharhinus leucas) • Region: Gulf of Mexico / Coastal Rivers & Estuaries • Era/Focus: Modern species; fossil tooth ID • Tooth ID: Broad, triangular crown with coarse serrations; thick neck and solid root built for power rather than finesse • Fun Fact: Bull sharks are one of the few species that can swim far upriver—found hundreds of miles inland thanks to their ability to regulate salt levels. They’ve been spotted in the Mississippi, the Amazon, and even Lake Nicaragua!
Rugged, fearless, and full of surprises—this card embodies the untamed edge of your pocket museum.
