WHEN THE TIDE IS OUT THE TABLE IS SET
Have you ever watched salmon jump, twist and leap their way past the many hurtles to return to their place of birth to spawn?
We are all familiar with the image of salmon returning to fresh water, to the rivers of their youth, to spawn and complete their lifecycle, in fact, it is one of the staple images of British Columbia. As adults, we bring our children to witness this cycle, rushing to the banks of our local rivers to watch as the adults, keen in their fight for reproduction and survival, struggle to complete their epic journeys against currents and predators. Arriving as they do, year upon year, season upon season, it seems to us that this is how it has been since time immemorial.
But we now have evidence that migration to the sea may be a relatively recent behaviour. Fossil beds at Driftwood Canyon, near Smithers, contain large numbers of fossil salmonid remains from the Eocene age, approximately 45 million years ago. What is interesting is that the fossil beds are filled equally with both juvenile and larger adults.
If these salmon were heading off to sea in their juvenile form and returning to spawn as adults we would expect to find an abundance of larger carcasses in the lake sediments and relatively few juveniles. Given the equal numbers, we can conclude that the salmonids of the Eocene, lived out their lifecycle as a landlocked species, the way Kokanee do today.

FOSSILS OF THE OLYMPIC PENINSULA
Aturia is an extinct genus of Paleocene to Miocene nautilids within Aturiidae, a monotypic family, established by Campman in 1857 for Aturia Bronn, 1838, and is included in the superfamily Nautilaceae in Kümmel, 1964.
Aturia is characterized by a smooth, highly involute, discoidal shell with a complex suture and subdorsal siphuncle.
Their shells are rounded ventrally and flattened laterally; the dorsum is deeply impressed. The suture is one of the most complex within Nautiloidea. It has a broad flattened ventral saddle, narrow pointed lateral lobes, broad rounded lateral saddles, broad lobes on the dorso-umbilical slopes, and a broad dorsal saddle divided by a deep, narrow median lobe.
The siphuncle is moderate in size and located subdorsally in the adapical dorsal flexure of the septum. Based on the feeding and hunting behaviours of living nautiluses, Aturia most likely preyed upon small fish and crustaceans. It is well worth exploring the exposures at Clallam Bay. The local clay quarry is on private land so you would need to seek permission. I have also seen calcified beauties of this species collected from river sites within the Olympic Peninsula range, though I have not explored these myself.

INSPIRATION: MOR-PHAR
That legacy carries on in the like-minded community of those I write, kayak and fossil collect with. Amazing people who fill me with wonder as they take in the beauty, rugged strength and delicate balance of this imperfect yet utterly perfect world.

FOSSIL COLLECTING 007-STYLE
Past trips have included grizzlies at close quarters. This trip we saw fresh tracks and scat, but the bears were actively avoiding our camp, just leaving enough evidence to give us the heads up that this is their territory.
Over the course of the week we collected beautiful marine specimens and saw a buck with a sexy set of horns, flocks of Franciscans and a majestic lone wolf.
The area is home to active research by UBC paleontologist, Louise Longridge and boasts abundant marine fauna - ammonites, bivalves, belemnites and have a chance to see the Triassic-Jurassic boundary – a rare treat.
As with all fossil collecting, our search for treasure has a higher goal. All of our finds are lovingly photographed, catalogued and available for study. If fossils are your thing, visit www.bcfossils.ca to find a local society and get on out there.
