Scientists Pussenkova pedagogical University in China, found in Western Australia the traces of the most ancient forms of complex life living on the land. The age of the organism, which refers to slime mold, is estimated at nearly two billion years. About it reported in a press release on Phys.org.
Fossil Myxomitodes stirlingensi represents a trace in the form of studs, which was discovered in Australian rocks sterling ridge. Initially it was thought that it could leave either a marine animal, such as worms or giant shell ameboidy of the genus Gromia, or a natural phenomenon (gas bubbles). However, a new study has shown that the most likely candidate are the type of slime mold myxomycetes (Mycetozoa), which lived on land in the Paleoproterozoic era (2.5 to 1.6 billion years ago), together with the cyanobacteria and microscopic fungi.
Although the slime mold are not multicellular organisms, scientists believe that Myxomitodes stirlingensi could contribute to the development of mnogoletnei.
Mycetozoa is Laboratorny organism, living in soil and preying on bacteria and other microorganisms. In conditions of deficiency of mineral substances form pseudoplasmodia slime mold — multinucleate vegetative body capable of active movement. After that, he forms spores resembling fruiting bodies of fungi. After a while, the shell of the sporophores is broken, releasing the spores.
