Coloured engraving of a Stegosaurus dinosaur

Stegosaurus. Coloured engraving from 1881 of a man viewing a fossil Stegosaurus dinosaur skeleton. Stegosaurus ("roofed reptile") was a herbivore that lived about 150 million years ago during the Jurassic period. It was about 6 metres (m) long and 2.5m high at the hips; it weighed about 1.5 tonnes. The distinctive broad spines running in two rows along its back are thought to have helped control body temperature by radiating or absorbing heat. Stegosaurus defended itself with the long spikes on its tail. Stegosaurus had a tiny brain in relation to its size. The first Stegosaurus skeleton was described in 1875

Coloured SEM of follicles in a human thyroid gland

Thyroid gland. Coloured scanning electron micrograph (SEM) of a section through a healthy human thyroid gland. The large follicles (top left & lower right), are lined by cuboidal secretory epithelial cells (red), which are secreting the thyroid hormones T3 (triiodothyronine) and T4 (thyroxine). Layers of epithelial cells (green) surround the follicles. The thyroid follicles are filled with a liquid called thyroglobulin or thyroid colloid, which is a storage form of the thyroid hormones. When inactive, the follicles are distended and the secretory cells flattened. The thyroid, an endocrine gland in the neck, regulates energy levels. Magnification unknown
