• Ammonites have a wide range of size. Specimens have been found ranging from less than a centimeter to 2 meters in diameter. Early ammonites, until the middle Jurassic, were smaller, usually less than 9 inches or 23 centimeters. These fossils come from the Mahajanga River Basin, near the village of Ambatolafia of northwest Madagascar (left), located in the former province of Mahajanga/Majunga. They date from the Early Cretaceous period, Albian age (~100 to 113.0 million years ago)
• Chemical Composition: CaCO3 - Complex with impurities; Hardness: 3.5-to-4-Hardness; Mineral Class: Organic-(Fossil); Color: Brown, Gray;
• The different suture patterns tell us what time period the Ammonite is from. Geometric - numerous undivided lobs and saddles; eight lobes around the conch is characteristic of the Paleozoic Ammonites. Ceratitic - lobes have subdivided tips; giving them a saw-toothed appearance and rounded undivided saddles - Triassic Ammonites. Ammonitic - lobes and saddles are fluted; subdivisions are usually rounded instead of saw-toothed - characteristic of the Jurassic and cretaceous Ammonites.
