Scientists Identify Prototaxites as an Alien Multicellular Organism AsatuNews.co.idSee Full Coverage on Google News
Recent scientific analysis of 400-million-year-old fossils has led researchers to conclude that the mysterious organism known as Prototaxites was neither a plant nor a fungus, but rather a distinct, foreign form of life. This discovery reshapes our understanding of early terrestrial biology and the evolution of multicellular eukaryotes.
First discovered in 1859, Prototaxites existed during the Silurian and Devonian periods, roughly 420 to 350 million years ago. For over a century, the organism eluded classification. As the fossils resemble petrified wood and feature concentric rings similar to growth rings in trees, early interpretations were varied. In 1859, John William Dawson identified a specimen—originally found in 1843 by Sir William Edmond Logan in Quebec’s Gaspésie region—as a conifer partially decayed by fungi. The name Prototaxites itself translates to “first yew,” reflecting this early belief that it was a primitive conifer.
However, later microscopic examinations by William Carruthers in 1872 challenged this theory. Carruthers observed that the organism lacked plant cells and instead possessed tubular filaments reminiscent of fungal mycelium. Despite these clues, the organism did not fit neatly into the categories of plants, animals, fungi, or lichens.
According to research, Prototaxites was the largest contiguous organism on land until the emergence of the first large trees in the mid-Devonian period. This means that the earliest land-based animals and plants evolved in the shadow of these massive structures. The largest known specimen is estimated to have reached 8.80 meters in length with a diameter of 1.37 meters.
The identification of Prototaxites as a unique type of multicellular eukaryote provides critical insight into the diversity of life on Earth before the dominance of modern flora. Understanding these extinct life forms helps scientists map the biological milestones that allowed complex life to thrive on land.
