A strange plant that exists since the first walk of animals can satisfy water in a severe water from water from meteorites from the ground. As well as the key to understanding the ecosystems today, the fossilizes left in the plant can light the climate and water systems in dinosaurs.
Almost all oxygen atoms in the water have eight neutrons, but some are rare, EXECUTIVE ISOTOPES with nine or 10 neutrons. If the water evaporates, the lesser isotopes turn more than the greater than more than, make the Change ratio in a predictable manner. Scientists can use it to track history to a particular water sample, as if water comes from the ground or from the fog, however the plant has passed through the plant before.
However, because more stressful isotopes occur in a small amount, it is difficult to gather good data on how to change the Isopope’s obsessions for scientists to explain.
If sampling water from deserts and animals, Zachary sharp At the University of New Mexico and his associates found their data was not suited to expected from models based on laboratory readings.
Evidency and his companions thought they had solved the problem thanks to the unusual plants called Horsheils, growing in the period from 400 million years ago, about 400 million years ago, and there were holes that had passed. “It’s a martter-high cylinder with a million holes in it, the same is launched. It’s a wonderful engineering,” as sharp. “You can’t do anything like this in a laboratory.”
If the water moves each part of the horsepail stem, it prompts, at times as it passes through the plant. The sharps and his fellows were shot by water in many points along the stem of smooth horsheils (Smooth smooth) Growing near Rio Grande in New Mexico.
When the water comes to the top of the stem, the isotope ratio is unlike other water found in the world. “If I saw this sample, I would say it from a meteorite, because it was not from Gechemistry in Prague,” Czech Republic, on 7 July.
With these measurements of Horsenail, the sharp and his team can calculate how the ratio of water isotope changes to nearly situations to make it more accurate.
If they re-edit their desert plant data with updated models, their observations suddenly are lacked. Important thoughts that these qualities may involve other explanations also for observations, especially in desert environments.
Old horsetails – growing up to 30 meters high, higher than descendants today – can provide more severe isotope systems and can be understood. Small grains like the sand called the phytoliths of the Horsetail stem, which can endure so far, there are different signs of air, because it affects the amount of aliasing. “We can use it as a waraeo-hygrometer warning (hygroma (which is relatively cool,” as sharp.
