About the Item

Madagascar Jurassic - Cretaceous Period, 200 - 145 million years old Dimensions: 7.75 × 6.5 × 1.75 in./ 19.5 × 16.5 × 4.5 cm Weight: 3 lbs 2 oz/ 1.366 kg Height on custom display stand: 10.25 in./ 26 cm In this example, the complex pattern of sutures that separated the air chambers, are numerous and closely spaced. There are traces of the creamy original shell in a few small areas. One side has retained several air chambers surfaced with druzy by the fossilization process while four neighboring chambers completely filled with crystals instead. Ammonites were cephalopods that resembled a squid with a shell. The predatory mollusks had eyes, tentacles, and spiral shells resembling a nautilus shell. Ammonites are closely related to octopus, squid, cuttlefish, and modern nautilus. Nautiloids both preceded and survived ammonoids after the later became extinct. Ammonites appeared in the fossil record about 240 million years ago, with the last descendants disappearing from the record 65 million years ago, at the end of the Cretaceous period. The last photo shows four whole ammonites for comparison. They range in size from 5.5 - 9.25 inches tall (14 - 23.5 cm). The example in this listing is second from left.
