Natural History Course

Walking through the immensity of the Museum of Natural History, in Upper West Side. Every room another wonder of our Cosmos.

Megaloceros

Megaloceros (Greek: μεγάλος – megalos + κέρας – keras, meaning “Great Horn”) may be the largest deer ever to have lived. It belongs to the group called artiodactyls (Greek: άρτιος – ártios + δάκτυλος – dáktylos, meaning ‘even finger/toe’) – hoofed mammals that usually have an even number of toes. Generally, only male artiodactyls have antlers. In living deer, they are used during the mating season for wrestling with other males and attracting females. Then, they are shed. This means that Megaloceros regrew its enormous antlers every year!

Stenomylus hitchcocki

Stenomylus (Greek στενός – stenos “narrow” and μύλος – milos [latin: mola] “molar” meaning ”narrow tooth”. This group of camel skeletons was buried in dune sand in western Nebraska 22 million years ago. These individuals are only some of the numerous completely preserved camel skeletons that were found together at a site in Agate Springs National Monument. Stenomylus lived in a region where dune fields extended widely. It was relatively primitive in its body skeleton, but had the more advanced feature of very high-crowned teeth – presumably to cope with sand-laden food, which rapidly wears down the teeth. 

If I understood correctly, ”hitchcocki” was added in honour of Dr. Edward Hitchcock, a geologist and President of Amherst College, whose Ichnology Collection of dinosaur footprints and tracks is invaluable (read more about it here).

 

Mammuthus

Mammoths were widespread during the Ice Ages. Some had woolly fur to keep them warm. This is a ”non-woolly” mammoth that lived in southern parts of the United States, which were not covered by glaciers. Like living elephants, Mammoths had trunks. We can’t see it on this skeleton, because soft parts are rarely preserved as fossils. But we can see where the trunk was attached, at the large single opening high on the front of the skull. The Greek myth of one-eyed giants, the Cyclops, may have arisen when ancient people found fossil provoscidean skulls and mistook this nostril opening for an eye socket. Most mammoths died out by 11.000 years ago but a few somewhat dwarfed forms persisted until about 3.000 years ago on remote arctic islands.

This stuffed beauty
(although I instinctively dislike stuffed animals)

Creatures of the sea hanging in mid-air
And those that came from the cold
