Scientists have discovered a large group of Kodak fossils from the early 2nd generation in Yangquan, Shanxi Province

Li Associate Researcher and others in Yangquan City, Shanxi Province, China, the first two stacks of Taiyuan group in the upper layer of a layer of sandstone found a group of wood fossils. According to statistics, the wood fossil group consists of 211 large Kodak plant stems.
the results have been published online in Palaeoworld.
it is learned that the discovery of the wood fossil group has attracted the attention of the local government, Yangquan City Planning and Natural Resources Bureau as a key protection object, to build a fossil heritage park and museum on this basis.
The researchers introduced that Koda is a kind of dead naked plants, in the late charcoal world - the second-largest period, the global widespread distribution, is one of the dominant elements in the land vegetation during this period, is also an important coal plant.
The leaf fossils of Koda plants are widely distributed in the late charcoal-late 2nd laminated formations in the north of China, and are often interpreted as tall trees, playing the role of canopy vegetation in ancient forests.
But their stem fossils are relatively rare in the Huaxia plant area, and their internal anatomy and habits are poorly understood compared to the european and American flora of the same period;
Researchers found that the stem in the fossil group preserved a separate myelin and dense wood-type secondary wood, of which, the diameter of more than 30 cm stem a total of 90, the thickest stem base diameter of up to 1.36 meters, based on the stem stem diameter of the value calculated that such plants up to 43.54 meters, is currently found and reported in the country's largest individual stem dry fossils.
at the same time, there were no growth wheels in stem wood, including fossil formations with coal seam dew, indicating that the climate in Yangquan area was humid and stable during this period, with no significant seasonal changes.
In addition, 16 fossil timbers, together with their complex roots, are preserved in the triage sandstone of the river on the delta plain, indicating that these plants originally lived in the riverbank zone;
this study was jointly funded by the National Natural Science Foundation of China, the China
Strategic Pilot Science and Technology Special (Category B), the National Key Laboratory of Modern Paleontology and Strata, and the China
Youth Innovation Promotion Association.
