I’m sorry we have been stuck on the lugubrious story of Oisín and Niamh for so long. To make up for it, here is one of my own paintings…and it isn’t just any painting: in fact it is a special painting which symbolically represents this blog. If you let your eye wonder through the composition, you will recognize many of the familiar themes and topics of ferrebeekeeper. Space is represented by a golden planet with Saturn-like rings, and by a rocket. Additionally, the entire composition takes place in outer space (as does everything–if you think about it). Against a backdrop of nebulae and swirling galaxies a domestic turkey takes wing and a school of belemnites (long vanished mollusks which are related to squid, octopuses, and cuttlefish) use their own jet propulsion to swim among the stars. A blue Chinese ewer made of porcelain floats in the bottom left corner beneath a swarm of eusocial bees which are issuing from a gothic beehive on the back of a great green river catfish. The goddess Hecate, the strangest and most evocative chthonic deity of ancient Rome brandished torches and a venomous serpent. Growing in the nothingness beside the witch goddess, a poisonous monkshood represents gardens (and poisons). In the center of the composition is a fearsome Andrewsarchus—the largest mammalian land predator. The mighty (albeit extinct) beast bears an ornate cobalt cake plate with a great glistening honey bundt cake. The wheat in the cake represents agriculture (as do the turkey and the bees), but beyond that, the cake’s toroid shape hints at larger cosmological mysteries. Taking a step back, the painting is composed of colors and it is itself visual art, the symbolic representation of humankind’s enduring search for meaning.
I have left politics out of the composition as a matter of good taste. Also trees did not make it into the painting because who’s ever heard of a tree in space?
In the summer of 1923, Kan Chuen Pao unearthed an enormous skull from the baking Gobi desert of Mongolia. Pao was a member of a paleontology expedition led by Roy Chapman Andrews, a world famous explorer, adventurer, and naturalist who, during the course of his career, rose from being a janitor at the American Museum of Natural History to being its director. The skull they found was an enigma—the creature was a mammal with immensely powerful jaws but blunt peg-like teeth. No substantial bones were found other than the skull sans jaw (nor have any further specimens ever been discovered). The skull was discovered in sediments deposited during the late Eocene, the sweltering summer epoch when most extant mammalian orders evolved, so it is probably 36 to 40 odd million years old. Andrews was immediately of the opinion that it was a huge carnivore, but what sort of creature was it really?
The creature was named Andrewsarchus mongoliensis in honor of Adrews and his expedition. Andrewsarchus may have been the largest mammalian carnivore ever (although short faced bears might have been larger). The one skull, currently in New York, measures 83 cm (33 inches) long and 56 cm (22 inches)wide–which suggests the animal may have been 3.4 meters (11 feet) long and nearly 2 meters (6 feet) tall at the shoulders. Such a creature could weigh more than 1000 kg (2200 lb).

But Adrewsarchus may not have been a carnivore: ever since the beginning of the jazz age, Paleontologists have argued about the monster’s diet. Andrewsarchus lived along the coast of the eastern Tethys Ocean, a sea which was dried out and destroyed when the Indian subcontinent barreled into Asia during the late Eocene/Early Oligocene.
Some scientists believe the creature was a hunter which captured the giant land animals of the time. Other scientists believe the animal was a scavenger which lived on the rotting carcasses of primitive whales and beached sea turtles. Another group feels that the creature fed on huge beds of shellfish, and a final school holds that the animal was even larger than believed and was at least part-herbivore!
The taxonomy of Andrewsarchus is equally confusing. The great skull was initially classified as a giant creodont (an extinct order of alpha-predators which share an ancestor with today’s carnivore). The first scientific paper about the creature by great paleontologist and…um, eugenicist, Henry Fairfield Osborn, states, “An outline sketch of the skull was sent in a letter to the Museum, from which Dr. W. D. Matthew immediately observed its real affinity to the primitive Creodonta of the family Mesonychidae.”
Later scientists have been less certain about lots of things than Osborn was and Andrewsarchus’ place in the mammalian family is now unclear. A consensus is emerging that the great creature shared common ancestors with the artiodactyls (like hippos, deer, and pigs). Perhaps its heritage provides insights into the link between the artiodactyls and their close (yet oh so distant) cousins the whales.

Whatever the case is, these giant hoofed creatures with their immense powerful maws must have been amazing and terrifying to behold. Their fate seems to have been sealed as the Tethys closed and the Gobi basin dried out, but, whenever I think of the harrowing deserts of Mongolia and China, I imagine their fearsome toothy spirits towering over the other strange ghosts of that haunted place.
