Stromatolite Ancient Life Large Slab Display Specimen
This stromatolite specimen is called Chlorellopsis coloniata Reis,
is an Eocene stromatolite. This spectacular, large slab has well preserved laminations and makes a dynamic addition to any serious fossil collection (especially one on stromatolites or early life).
This Eocene stromatolite is named Chlorellopsis colonia Reis.
It grew in a number of phases that were related to the depth of the freshwater that they inhabited. This one is from Lake Gosiute, Ft. Laclede bed, Laney member, Bridger A-B of Green River Eocene and is a marvel of preservation.
The fascinating story of ancient freshwater Lake Gosiute of SW Wyoming's Eocene is larger than the lake itself (45,000 sq.mi.) It was a stromatolite heaven some 45-52 million years ago. Volcanic ash filled in the very shallow lake covering it a mile deep in ash that has since eroded off to expose the lake bed of today. The silica rich ash provided excellent preservation of the many phases of the Chlorellopsis colonia Reis
stromatolites of the shallow (60' maximum depth) lake.
Lake Gosiute is a very historical event in North America's fossil record. Flamingo's (Aves Phoenecopteridea)other birds, tithanotheres, running rhino's, creodonts, oreodonts all lived here once. Tuffa mounds, varves, paleo soils, giant turtles, crocodiles and other inhabitants make it a fascinating place for study. Eohippus horse was found there.
3.5 billion years ago stromatolite colonies flourished in Australia. (see our apex chert) From around 3-1.8 byo stromatolites were instrumental in making the oxygen we breathe today.
