Tooth size in South American sea lions reflects historical shifts in population abundance

PALEONTOLOGY
A new study published in PeerJ reveals that the teeth of South American sea lions (Otaria byronia) hold valuable clues about past population dynamics. Researchers from the Instituto de Biología de Organismos Marinos, the Centro para...

Here’s a look at moon landing hits and misses
