ISOGRAPTUS MAXIMUS
Graptolites (Graptolita) are colonial animals. The biological affinities of the graptolites have always been debatable. Originally regarded as being related to the hydrozoans, graptolites are now considered to be related to the pterobranchs, a rare group of modern marine animals.
The graptolites are now classed as hemichordates (phylum Hemichordata), a primitive group which probably shares a common ancestry with the vertebrates.
In life, many graptolites appear to have been planktonic, drifting freely on the surface of ancient seas or attached to floating seaweed by means of a slender thread. Some forms of graptolite lived attached to the sea-floor by a root-like base. Graptolite fossils are often found in shales and slates. The deceased planktonic graptolites would sink down to and settle on the sea floor, eventually becoming entombed in the sediment and are thus well preserved.
Graptolite fossils are found flattened along the bedding plane of the rocks in which they occur. They vary in shape, but are most commonly dendritic or branching (such as Dictoyonema), saw-blade like, or "tuning fork" shaped (such as Didymograptus murchisoni).
This fellow is pure "Bat Sign" with his showy "wings" looking like something out of a DC Comic. He's also received a nod as the Panem symbol in Hunger Games and been described as having eagle or angel wings. No matter how you interpret his symbolism, there is not doubt that he is spectacular. He is in the collection of the deeply awesome Gilberto Juárez Huarachi from Tarija, Bolivia.

SUMAS EOCENE SITE
Once the skies cleared, hikers found plant impressions in the rock and alerted the local paleo community. I was invited to tag along on a trip to photograph the site while George Mustoe took moulds of the palm trunks and trackways.
The slide site at Sumas Mountain revealed many large exposures of fossil plants. Some exposures were 10 feet across. There was great excitement at seeing shorebird tracks and trackways of the large flightless bird Diatryma. Many of these finds can now be seen at the Burke Museum in Washington State. While less abundant, evidence of the animals that called this ancient swamp home are also found here. Rare bird, reptile, and mammal tracks have been immortalized in the soft muds along ancient riverways.

MOON RAVEN TOTEM AT SAXMAN TOTEM PARK
Moon Raven Pole at Saxman Totem Park |
The art of totem pole carving was a luxury that experienced its heyday in the mid-1700s to the late 1800s.
In the late 1800s, Tlingits from the old villages of Cape Fox and Tongass searched out the Saxman site as a place where they could build a school and a church.

OYSTER: TLOXTLOX
While rare today, these are British Columbia’s only native oyster. Had you been dining on their brethren in the 1800s or earlier, it would have been this species you were consuming. Middens from Port Hardy to California are built from Ostrea lurida.
These wonderful invertebrates bare their souls with every bite. Have they lived in cold water, deep beneath the sea away from the suns rays and heat? Are they the rough and tumbled beach denizens whose thick shells have formed to withstand the pounding of the sea?
Is the oyster in your mouth thin and slimy having just done the nasty spurred by the warming waters of Spring? Is this oyster a local or was it shipped to your current local and if asked would greet you with "Kon'nichiwa?" Not if the beauty on your plate is indeed Ostrea lurida.
We have been cultivating, indeed maximizing the influx of invasive species to the cold waters of the Salish Sea. But in the wild waters off the coast of British Columbia is the last natural abundant habitat of the tasty Ostrea lurida in the pristine waters of Nootka Sound. The area is home to the Nuu-chah-nulth First Nations who have consumed this species boiled or steamed for thousands of years. Here these ancient oysters not only survive but thrive — building reefs and providing habitat for crab, anemones and small marine animals.
Oysters are in the family Ostreidae — the true oysters. Their lineage evolved in the Early Triassic — 251 - 247 million years ago.
In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, an oyster is known as t̕łox̱t̕łox̱. I am curious to learn if any of the Nuu-chah-nulth have a different word for an oyster. If you happen to know, I would be grateful to learn.
