Mit dem obskursten #Fossil meiner #Sammlung geht das!
#Prototaxites - ein Lebewesen voller #Rätsel
Man hielt es für die erste baumartige Pflanze 🌲, einen kolossalen #Pilz 🍄🟫 oder eine 9-Meter #Flechte 🪸
Vermutlich war es eine eigene Gruppe von Eukaryoten 🦠, die im Devon ohne heutiges Gegenstück ausstarb.
#Versteinert ist hier auch das Urmoos Cooksonia.

Let's go back to the best fossils and really look and think about what we are seeing and what it could mean with this organism.

Giant, #Ancient Life Form Doesn’t Fit Into Any Known Branch of Life
Scientists have debated where #Prototaxites belong in tree of life for over a century, but now a new study suggests it might represent a whole new branch.
Researchers analyzed #fossil of Prototaxites species called Prototaxites taiti and concluded that it belonged to now-extinct lineage of multicellular #terrestrial #eukaryotes (organisms, including all animals and plants, whose cells contain a nucleus).

Prototaxites represents the first giant organisms to live on the terrestrial surface, reaching sizes of 8 metres in the Early Devonian.
It was an extinct lineage of #multicellular terrestrial #eukaryotes.
Assignments to groups of multicellular algae or land plants have been repeatedly ruled out leaving two major alternatives: #Prototaxites was either a #fungus or a now entirely extinct lineage.
The latter hypothesis seems more plausible based on nrw evidence.

Bizarre #fossil may have been an entirely new type of #life. Chemical analysis suggests the 400-million-year-old fossil #Prototaxites was neither plant, animal or fungus – hinting at a mysterious life form that went extinct long ago. http://archive.today/2025.03.21-191932/https://www.newscientist.com/article/2473272-bizarre-fossil-may-have-been-an-entirely-new-type-of-life/ #science #palaeobotany #paleobotany #biology #botany #mycology #taxonomy
