In 1699, accompanied by a shipboard artist, William Dampier conducted the first scientific investigation of the plants and animals of Australia (then known as New Holland). From there he and his crew...
A drawing of Phoenix from the Right Whale Catalog documents her callosity pattern and other identifying marks. More about whales can be found in our Tale of a whale featured story .
Like the modern nautilus, this relative of modern squid hunted from inside the safe haven of a protective shell. Ammonites went extinct around the same time as the dinosaurs—65 million years ago...
