A flower-spike of Meadowsweet (Filipendula ulmaria) growing in its typically wet, boggy habitat in central Scotland in mid-summer. The species has a long history of herbal use, traditionally being used as an anti-inflammatory, antiseptic, diuretic, and tonic since ancient times in druidic England.
A 3-D computer illustration of Eurypterus remipes, more commonly known as a Sea Scorpion, from the mid Ordovician to late Permian (460 to 248 million years ago). Eurypterids are an extinct group of arthropods that are related to arachnids and include the largest known arthropods to have ever lived. They went extinct during the Permian–Triassic extinction event 252.17 million years ago. Their fossils have a near global distribution. Though purely an artistic interpretation, the structure of the animal is inferred through fossil images and scientific notation of what the species may have looked like within the environment in which they existed.
