Summary
Danish Megalodon vertebrae lost since the 1980s have been rediscovered, letting researchers reexamine some of the largest shark vertebrae ever found from a specimen unearthed in the late 1970s.
9-inch vertebrae from the 10.8-million-year-old fossils support a 2025 estimate that the animal reached about 24.3 meters, the largest scientifically defensible size so far, though researchers say a complete skeleton is still missing.
Micro-CT scans found at least 64 growth bands, indicating the shark was at least 64 years old; a growth model suggests it may have lived as long as 96 years.
Basking shark scales and gill structures preserved with the vertebrae may be stomach contents, potentially the first direct prey evidence tied to Megalodon and a sign it fed on large marine animals.
Because shark skeletons are mostly cartilage and rarely fossilize, the Danish specimen remains a rare anchor for debates over Megalodon's maximum size, growth and feeding ecology.
