study uses ancient plant to decode #Earth's #climate history
the study focuses on #horsetails — hollow-stemmed #plants that have thrived on Earth for more than 400 million years. The team’s findings reveal that #water traveling through these plants undergoes such intense natural #distillation that its #oxygen #isotope ratios resemble those found in meteorites or in extraterrestrial materials.

Really quite impressive thicket of Great Horsetail (Equisetum telmateia) in this railway siding at Three Bridges. Fairly easy to ID even at a distance because it’s biiiig (1 metre tall or more) and has very pale, almost white jointed stems.

I got to make a fun dino animation for the Zoological Museum of the University of Zurich! https://youtu.be/Sm2kh_VQv9s

Field Horsetail (Equisetum arvense) grows fertile shoots in early spring and the typical non-fertile, many-branched green stalks later in the year.

Relatives of the giant #horsetails that used to grow as tall as trees, this ancient plant can be thought of as a living fossil. Their ancestral line dates back over three hundred million years.... We marvel over long-lived trees, but spare a moment to admire some horsetails. #TsoukeTerritory
