LINKING TIME: AMMONITE INDEX FOSSIL
They filled our world's oceans back in the day. We find ammonite fossils (and plenty of them) in sedimentary rock from all over the world. In some cases, we find rock beds where we can see evidence of a new species that evolved, lived and died out in such a short time span that we can walk through time, following the course of evolution using ammonites as a window into the past.
For this reason, they make excellent index fossils. An index fossil is a species that allows us to link a particular rock formation, layered in time with a particular species or genus found there. Generally, deeper is older, so we use the sedimentary layers of rock to match up to specific geologic time periods, rather the way we use tree rings to date trees.

COUGARS CONCOLOR: BADI
They are the most widely distributed land mammal in the Western hemisphere and yet we never seem to see them. They lead solitary lives and are excellent at avoiding humans. They see us far more often than we see them — boasting a field of vision spanning 130 degrees.

BOAS, YALIS AND THE RAVEN GWA'WINA CYCLE
“Mrs. Spencer was very gracious and told me many stories,” Boas wrote to Krackowizer, “which I recorded later in the evening.”
The star of the drama was Raven, scheming, ravenous, bumbling in his arrogance toward ever-greater disgrace, yet always surviving, evolving, and through his accidents and exploits establishing the present state of affairs.
Born before the earth had acquired its form, it was Raven—Old One, Great Inventor, Chief of the Ancients, Heaven Maker, Giving to the End, Going Around—who established the tools and forms of existence.
With the world veiled in darkness, Raven stole the box that held the sun and opened it, lighting the world by his ingenuity.
He made man from grass and elderberry bushes, brought salmon to the people, fed the rivers with eulachon. He established the shapes and traits of his fellow animals and gave them their present powers and appearances. And though affairs could hardly change as radically in contemporary times as in the days of beginning, by his actions and infractions Raven pointed toward a way of being human. “So many stories are told about him,” Boas remarked during his first visit to the coast, “that they have a saying that human life is not long enough to tell all of them.”
Every First Nation of the Northwest Coast was woven into the fabric of the Raven Cycle through the warp and weft of a storytelling practice that linked speakers and listeners—messengers and mediums—within a pattern of call and response. There were no galleries around the fire, no lines dictating who paid and who performed. There were no observers, no outsiders, no Others. People did not merely listen to the Raven Cycle; they took part, asking questions, repeating refrains, goading the storyteller toward feats of ingenuity.
There was saltiness and sport in the Raven tales, sex and waste, greed and hate. The bards were like Raven: they begged, borrowed, stole, and in doing so created. They were origin poets who fostered possibilities by defying the rules of the system they had made.
The stories they told, often ending in just-so pronouncements—explaining, say, how wolves had come to behave so diffidently around humans (“they really became wolves after this,” one storyteller put it)—wove a fabric of thought that embraced every notable rock, tree, and stream in the neighbourhood, encompassing the human community within an animate cosmos.
"I remember with the greatest pleasure many trips in colourful canoes with Indian guides who did not stop telling tales,” Boas wrote in one account of this storytelling culture for a German audience.
“It was that mountain peak which alone reached above the waters during the great flood, and from this peak, the earth was populated again. Here, the battle took place in which the stone giants were outwitted and killed by the brave Indians. A dangerous rapid, formed in prehistoric times in a narrow strait, reminds us of the Son of God, who killed and sank a dangerous sea monster into the ocean at that place. Each strange place is woven into a legend.”
