AGASSIZ

A wonderful replica of Furo Philpotae (Agassiz) fossil fish from the Jurassic of Lyme Regis, UK by Natural Selection Fossils.

The original specimen that this replica is made from is the most complete ever found and considered the best preserved in the world. This beauty with a ton of exquisite detail measures approximately 87 cm in length.

GINKO BILOBA

Each year, I grow Ginko and Metasequoia to plant on Earth Day. They serve as an homage to the environment and a offering to Gaia for a cleaner, kinder world.

BONE TO STONE

Calcium carbonate reacts with water saturated with carbon dioxide to form the soluble calcium bicarbonate. Bone already contains calcium carbonate, as well as calcium phosphate, Ca2, but it is also made of protein, cells and living tissue.

Decaying bone acts as a sort of natural sponge that wicks in the calcium carbonate displaced from the shells. As protein decays inside the bone, it is replaced by the incoming calcium carbonate, making the bone harder and more durable.

AMMONITE BEAUTY

Varying in size from millimeters to meters across, ammonites are prized as both works of art and index fossils helping us date rock. The ammonites were cousins in the Class Cephalopoda, meaning "head-footed," closely related to modern squid, cuttlefish and octopus. Cephalopods have a complex eye structure and swim rapidly. The ones shown here are from a Sinemurian site I visited a few years back high up in the Canadian Rockies.

Ammonites used these evolutionary benefits to their advantage, making them successful marine predators. I shared some ammonites with my wee paleontologist cousins this weekend, Madison and Melaina. They were impressed with the amazing range of species and body styles. Their favorites were the ones from Alberta and England with their original mother of pearl still intact.

LATE OLIGOCENE SOOKE FORMATION

Desmostylus, Royal Ontario Museum Collection

The late Oligocene Sooke Formation outcrops at several coastal localities along the South-west coast of Vancouver Island. The most well-known and most collected of these are the exposures to the west of Muir Creek.

The formation contains marine fossils including a diversity of intertidal and near shore gastropods, bivalves, abundant barnacle (Balanus) plates, and rare coral, echinoid (sand dollar) and mammal (Desmostylus) fossils.

When these fossils were laid down, the Northeastern Pacific had cooled to near modern levels and the taxa that were preserved as fossils bear a strong resemblance to those found living today beneath the Strait of Juan de Fuca. In fact, many of the Sooke Formation genera are still extant.

We find near shore and intertidal genera such as Mytilus (mussels) and barnacles, as well as more typically subtidal predatory globular moon snails, surf clams (Spisula, Macoma), and thin, flattened Tellin clams.

In several places, there are layers thickly strewn with fossils, suggesting that they were being deposited along a strand line. The rock is relatively coarse-grained sandstone, suggesting a high energy environment as would be found near a beach.

The outcrops at Muir Creek make for a great day trip. This is a family friendly site best enjoyed and collected at low tide.
