Vaquita are the world’s smallest and one of the most endangered species of whale, dolphin or porpoise on the planet. Found only in Mexico’s northern Gulf of California, the population has declined by more than 75% in the past three years and currently fewer than 50 vaquita remain.

Examination of an ancient fossil has given scientists another insight into the evolution of baleen whales such as humpback or blue whales.
