This is a great 147.5 gram fossilized Micraster from Rzezusnia, Poland.
Micraster is an extinct genus of echinoids from the Late Cretaceous to the early Eocene. Its remains have been found in Africa, Antarctica, Europe, and North America. Micraster was an infaunal echinoid living in a burrow below the sediment surface. The test (hard shell) is clearly bilateral and there is a deep anterior groove to take in water containing organic particles to the mouth. The tube feet keep a supply of nutrient-laden water moving into the burrow. The anus has a waste tube behind it.
Although dinosaurs are the most well-known fossil life forms, Equinoids are also a favorite among those familiar with Paleontology (the study of the development of life on Earth). The specimen measures 60x60 mm.
I ordered a Myanmar ruby of 1.85 ct. and a 1.2 ct. garnet. They processed my order the same day and the package showed up at home only two business days later. Beautiful gems, beautifully presented and excellent service. The website is a joy to peruse. I immediately ordered half a dozen more for a birthstone project. The best source i found for stones in Canada. Thanks Laura & Jean!
Très belle pièce. Je commence à collectionner les météorites et cette pièce est peu dispendieuse et va enrichir ma collection. Expédition rapide et excellente communication avec les gens de Canagem. AAA+++
It wasn't until I got a new UV light that I was able to see the amazing colour of this flourite. The specimen is very attractive in natural light, and crazy beautiful under 254nm UV! I love it!
