📖 Overview

In December 1938, museum curator Marjorie Courtenay-Latimer spotted an unusual fish among a South African trawler catch. J.L.B. Smith identified it as a coelacanth - a lobe-finned fish thought extinct since the Cretaceous. It was one of the century's most extraordinary biological discoveries and reframed the fish-to-tetrapod evolutionary story.
