As a late development of the dinosaurs Archeopteryx would have come extinct at the Cretaceous-tertiary boundary about 66 million years ago (when all … Its relationship with birds is clear, but it has similarities with dinosaurs too. Be sure to know the appearance of a eurypterid. Learn More / Page 2. We don't really know. The Solnhofen Limestone is a very fine-grained Jurassic limestone formed in a shallow tropical marine environment (probably a coral lagoon), where lime-rich muds slowly accumulated and permitted fossil material to be exceptionally well preserved. So how and when did these marvelous creatures go extinct? This was approximately 150 million years ago. PUBLISHED May 24, 2018.
