Living Fossils: 10 Plants & Animals With Staying Power
[ Filed under History & Trivia or in the Animals & Habitats category ]

For so-called “living fossils”, the maxim “if it ain’t broken, don’t fix it” would seem to apply. Surviving relatively unchanged for tens, even hundreds of millions of years, these very special plants and animals have each managed to find a successful ecological niche and have stuck with it.
Horsetails

Horsetails are an unusual group of plants that reproduce via spores instead of seeds. Now limited to a single genus, Horsetails were once the dominant plant of the prehistoric world, first appearing in the Devonian period approximately 375 million years ago. Today’s Horsetails, oddly enough, are poisonous to horses.

Kings of the Carboniferous period when giant dragonflies and six-foot long millipedes thrived in the planet’s supersaturated oxygen atmosphere, ancient relatives of Horsetails called Calamites soared up to 90 feet high as they competed for sunlight with the world’s earliest trees.
Monkey Puzzle Tree

Monkey Puzzle or Araucaria trees are an ancient species of evergreen conifer that is today only found in some parts of Argentina and Chile. The trees have oddly scaled branches – the scales are actually leaves – and have distinctive bark likened by some to reptilian skin. The trees are tough and hardy, and can grow to heights of 130 feet and diameters of up to 6 feet.

Samples of Monkey Puzzle trees were first brought to Great Britain in the early 19th century and by the 1850s the trees were being grown at botanical gardens. As for the unusual name, it’s said that a visitor to Pencarrow Garden in Cornwall, upon observing the odd tree, suggested that “It would puzzle a monkey to climb that”. Monkey Puzzle trees are often used by artists to ‘flesh out” prehistoric scenes, like the one above from the BBC TV series “Walking With Dinosaurs” that features an Allosaurus on the prowl.
