Detailed black-and-white illustration of the head and neck of a gigantic land tortoise labeled "Testudo microphyes." The tortoise's head is covered in large, distinct hexagonal and irregular scales, with textured, wrinkled skin along its thick neck. The eye is prominent and round, showing a glossy surface. The drawing emphasizes the rough, scaly texture and folds of the skin, highlighting the tortoise's massive size and ancient, rugged appearance. The image is part of an 1877 collection from the British Museum showcasing living and extinct giant land tortoises.

Historical illustration of a dolphin labeled "Delphinus Orca Linn." showing a dark gray, stocky body with lighter, cream-colored underbelly. Notably, the dolphin has large, rounded pectoral fins resembling ears, a prominent dorsal fin with a jagged edge, and a tail fin. The head is exaggerated with sharp, pointed teeth and a distinctively sculpted face, including a pronounced brow ridge and a green eye. A water spout arches above the dolphin’s head, indicating its aquatic nature. The style is detailed and textured, typical of 18th-century natural history engravings.

Has been a bit of a #bony day today in the collections - these two plates published in A series of engravings representing the bones of the human skeleton .. by John Barclay in 1819 perhaps being my favourites. Both engraved by E. Mitchell #rarebooks #skeletons #barebones

Just a 1399 unicorn watermark from a paper manufacturer from Valencia to make your day. Friends of #paperhistory know that these paper sheets of around 1400 are among the first sheets of European paper to appear on the market. European #bookhistory was a different game afterwards. #skystorians

Illustration of a lemur perched on a bare tree branch, holding onto a smaller branch with its hands and feet. The lemur has a rounded body covered in brown fur, a pale face with large, dark eyes, and small rounded ears. The tree trunk is depicted with detailed bark texture and small green leafy sprigs emerging from it. The background is plain, focusing attention on the lemur and tree. The style is a scientific, naturalist drawing from the late 18th century, showing anatomical features clearly for identification.

The aye-aye's distinctive spindly digits.

Surely one of the most exquisite zoological publications of the nineteenth century: Richard Owen's Monograph on the Aye-Aye (1863), with plates drawn by Joseph Wolf and lithographed by James Erxleben. Also a key statement of Owen's conception of evolution. (The @nhmlibraryarchives.bsky.social copy.)

A quokka standing on its hind-legs

One of the earliest European accounts of an Australian mammal was of a #quokka, by Willem de Vlamingh in 1696, here on #Rottnest - in fact, he named the island after them (Rottnest means Rat's nest in Dutch - of course it already had a Noongar name: Wadjemup). The account of the voyage... 1/2
