Two subclasses of cestodes are differentiated on the basis of the numbers of larval hooks, the Cestodaria being decacanth (10 hooks) and the Eucestoda being hexacanth (6 hooks). Collectively, 14 orders of cestodes have been identified according to differences in parasite morphology and developmental cycles.
Most meteorites originate between Mars and Jupiter, where a belt of asteroids has lingered for 4.5 billion years, since the solar system was young. No rock on Earth is as old as a meteoriteâall terrestrial material has been ground, melted, and reformed by plate tectonics. Meteorites have other, less common, origins. Meteor impacts on the moon or Mars can eject surface material into space that ends up on Earth. Last year a 10.5-ounce meteorite that originated on Mars fetched $94,000. A 4-pound lunar meteorite, the most expensive ever auctioned, sold for $330,000 in 2012.
LOCALITIES. MOLDAVITE is only found in the Czech Republic in the strewnfield areas of the Reis Impact Crater created by the impact of a meteorite/asteroid approximately 14.8 million years ago.These are some of the localities they are found in.his area has been extensivelly mined and there is not much being found n this area. Some of the nicest structured Moldavite pieces come from this locale. The Besednice site moldavites come from the primary bed for brickworks. Moldavites findings are quite abundant in the form of latch, drops and particles.
