TERRACOTTA WARRIORS

The Terracotta Army is a collection of more than 7,000 life-size figures depicting the armies of Qin Shi Huang, First Emperor of China, set in military formation found in an archaeological excavation near Xi'An, Shaanxi Province, China.

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.

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.

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.

GIANT'S CAUSEWAY: NORTHERN IRELAND

The Giant's Causeway is a spectacular expanse of interlocking hexagonal basalt columns formed from volcanic eruptions during the Paleocene some 50-60 million years ago.

Highly fluid molten basalt intruded through chalk beds which later cooled, contracted and cracked into hexagonal columns, creating a surreal visual against a dark and stormy Irish Sea.
