TANGIERS: ANCIENT TUSKS


During the Miocene and Pliocene, 12-1.6 million years ago, a diverse group of extinct proboscideans, elephant-like animals walked the Earth.

Most of these large beasts had four tusks and likely a trunk similar to modern elephants. They were creatures of legend, inspiring myths and stories of fanciful creatures to the first humans to encounter them.

Beyond our neanderthal friends, one such fellow was Quintus Sertorius, a Roman statesman come general, who grew up in Umbria. Born into a world at war just two years before the Romans sacked Corinth to bring Greece under Roman rule, Quintus lived much of his life as a military man far from his native Norcia. Around 81 BC, he travelled to Morocco, the land of opium, massive trilobites and the birthplace of Antaeus, the legendary North African ogre who was killed by the Greek hero Heracles.

The locals tell a tale that Quintus requested proof of Antaeus, hard evidence he could bring back to Rome to support their tales so they took him to a mound at Tingis, Morocco, where they unearthed the bones of a Neogene elephant, Tetralophodon.

Tetralophodon bones are large and skeletons singularly impressive. Impressive enough to be taken for something else entirely. By all accounts these proboscidean remains were that of the mythical ogre Antaeus and were thus reported back to Rome as such. It was hundreds of years later before their true heritage was known.

FOSSILS AND RED OCHRE


Around 45-50 million years ago, during the middle Eocene, a number of freshwater lakes appeared in an arc extending from Smithers in northern British Columbia, south through the modern Cariboo, to Kamloops, the Nicola Valley, Princeton and finally, Republic, WA.

The lakes likely formed after a period of faulting created depressions in the ground, producing a number of basins or grabens into which water collected - imagine gorgeous smallish lakes similar to Cultus Lake near Chiliwack, British Columbia.

The groaning Earth, pressured by the collision of tectonic plates producted a series of erupting volcanoes around the Pacific Northwest. These spouting volcanoes blew fine-grained ash into the atmosphere and it rained down on the land. The ash washed into the lakes and because of its texture, and possibly because of low water oxygen levels on the bottoms that slowed decay beautifully preserved the dead remains of plant, invertebrate, and fish fossils - some in wonderful detail.

In and around the town of Princeton, there are many places to collect. The fossils you find here are all middle Eocene, Allenby Formation and most have a high degree of detail in their preservation.

A crack of the hammer yields fossil maple, alder, fir, pine, dawn redwood and ginko fossil material. Several species of fossilized insects can be found in the area and rare, occasional fossil flowers and small, perfectly preserved fish. It is also home to one of the world's oldest bee's - a find by Rene Saveneye - naturalist and keen paleo hunter who will be much missed.
