  Megatherium - LoveToKnow 1911
MEGATHERIUM (properly Megalotherium), a huge extinct edentate mammal from the Pleistocene deposits of Buenos Aires, typifying the family Megatheriidae (or Megalotheriidae), and by far the largest representative of the Edentata.
Except, indeed, for its relatively shorter limbs Megatherium americanum rivalled an elephant in bulk, the total length of the skeleton being 18 feet, five of which are taken up by the tail.
The hind-foot is remarkable for the great backward projection of the calcaneum, and likewise for the peculiar shape of the astragalus; the middle toe alone carries a claw, this being of huge size, and ensheathed like those of the fore foot.

Megatherium americanum, a ground sloth, stood 12 feet tall, had 7-inch claws, and weighed close to 9,000 pounds.
Because all existing sloths are vegetarians and because Megatherium lacked the sharp killing teeth typical of carnivores, paleontologists have assumed that it, too, was an herbivore.
Fariña calculated that for an animal of Megatherium’s proportions to achieve maximum speed in a stabbing motion, the olecranon should be from three to five inches long--a close match to its actual length of about 4.75 inches.

 The smallest and most ancient Megatherium (Tardigrada, Megatheriidae)
It represents the earliest and smallest species of its genus and is the sister species of Megatherium americanum Cuvier, 1796 based on the following synapomorphies: very deep horizontal ramus of the dentary, prominent torsion of the femoral diaphysis, relatively concave medial and lateral femoral margins, and reduced patellar trochlea.
Megatherium was apparently adapted to a temperate climate, as opposed to the more tropical range occupied by Eremotherium Spillmann, 1948.
The discovery of the new species possibly indicates broad ecological similarity between the Pliocene Altiplano and the Argentinian lowlands, and that the clade may have originated on the Altiplano.

 DESIGN UP TO SCRATCH?
To Buckland Megatherium was an excellent creature to demonstrate the design of God for reasons, which shall become apparent.
Buckland pointed out that Megatherium was related to the sloths and then stressed that the sloths were "a family whose structure is very anomalous, and has been misunderstood by almost every naturalist including Buffon, even the immortal Cuvier himself."(p8) Cuvier had recently died of cholera and his death was deemed a great loss to science.
Buckland was, perhaps, the strongest scientific disciple of Paley and his lecture on Megatherium demonstrates a relentless searching for design in the most unpromising of animals.
