Horseshoe Crab and Crayfish, Triassic France by Douglas Henderson
“illustration for the book DAWN OF THE DINOSAURS, LIFE IN THE TRIASSIC (…) The image represents brackish pool deposits from the Gres a Voltzia Formation near the early Atlantic shore of Triassic France some 230 million years ago. Trapped in a transient pool are fragments of shore plants and various conifer limbs, leaves and a cone, together with the small fish Dipteronotus, a small crayfish, a horseshoe crab and numerous small jellyfish.”

“… the Staatliches Museum für Tierkunde Dresden commissioned Leopold to produce twelve models of sea anenomes. While these designs were based on drawings in books, Leopold was soon able to use his earlier drawings to produce highly detailed models of other species, and his reputation quickly spread. Leopold began selling models of marine invertebrates to museums, aquaria, universities and other educational bodies who wanted visual aids but were unable to satisfactorily preserve such animals…” (read more: Wikipedia)
May 22 is the International Day for Biological Diversity. This year the theme is marine biodiversity.
International Day for Biological Diversity was created by the United Nations to increase the understanding and awareness of biodiversity issues.
Images above from the Biodiversity Heritage Library (Smithsonian Libraries is just one of the many libraries that contribute to this collection, this item comes from our friends at the Museum of Comparative Zoology at Harvard.) The volume is entitled An attempt towards a natural history of the polype. Polyps belong to the phylum Cnidaria, which includes
many charismatic organisms such as hydras, sea fans, jellyfishes, sea anemones, corals, and the Portuguese man-of-war. Cnidarians all have some type of specialized stinging cell organelle. Cnidarians’ bodies typically take one of two forms: the polyp or the medusa. While the polyp form is adapted for a sedentary or sessile lifestyle, the medusa form is adapted for floating or free-swimming. Sea anemones and corals (class Anthoza) are all polyps.
