Enter the curious world of the monotremes. We’ll explore their ancient origins, meet the modern platypus and echidnas, and learn how these mammals form and care for their eggs. We’ll discover what their eggs are like, from size and structure to incubation, and peek into the nesting burrows and pouches where devoted mothers tend their fragile, hatchling young.

Reconstructing Mesozoic Bird Eggs Using Non-Invasive Methods

ByMichael Naghan

Reconstructing the size, shape, surface texture, and coloration of extinct Mesozoic bird eggs is challenging because actual egg specimens from Mesozoic birds are extremely rare. Paleontologists must rely on indirect, non-destructive methods to infer these characteristics for museum displays and scientific understanding. Here we outline key non-invasive methods and their applications, with examples from recent scientific literature.
