CENOMANIAN-TURONIAN IMPACT

Ichthyosaur and Plesiosaur by Edouard Riou, 1863

During the early Triassic period, ichthyosaurs evolved from a group of unidentified land reptiles that returned to the sea. They were particularly abundant in the later Triassic and early Jurassic periods before being replaced as a premier aquatic predator by another marine reptilian group, the Plesiosauria, in the later Jurassic and Cretaceous periods.

In the Late Cretaceous, ichthyosaurs were hard hit by the Cenomanian-Turonian anoxic event. As the deepest benthos layers of the seas became anoxic, poisoned by hydrogen sulphide, deep water marine life died off. This caused a cascade that wreaked havoc all the way up the food chain. At the end of that chain were our mighty predaceous marine reptiles.

Bounty turned to scarcity and a race for survival began. The ichthyosaurs lost that race as the last of their lineage became extinct. It may have been their conservative evolution as a genus when faced with a need for adaptation to the world in which they found themselves and/or being outcompeted by early mosasaurs.

FERNIE AMMONITE

Titanites occidentalis / Fernie Ammonite

This impressive big beauty is Titanites occidentalis, Western Giant, the second known specimen of this extinct fossil species.

The first specimen was discovered in 1947 in nearby Coal Creek by a British Columbia Geophysical Society mapping team.

Titanities is an extinct ammonite within the family Dorsoplanitidae that lived during the upper Tithonian of the Late Jurassic, some 152 to 145 million years ago.

ISOGRAPTUS MAXIMUS

This fellow is the graptolite, Isograptus cf. maximus, from the Piranha Formation, Middle Ordovician (Dapingian), Bolivia.

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. They are hemichordates, phylum Hemichordata, a primitive group that share a common ancestry with the vertebrates. Yes, you're looking at one of your oldest relatives!

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 seafloor, 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 no doubt that he is ONE spectacular specimen and currently in the collection of the deeply awesome Gilberto Juárez Huarachi of Tarija, Bolivia.

GOAT: CAPRA MAGICAL

Goats, Capra hircus, are a domesticated species of goat-antelope typically kept as livestock. 

They were domesticated from wild goats, C. aegagrus, from Southwest Asia and Eastern Europe. 

The goat is a member of the animal family Bovidae and the subfamily Caprinae, meaning it is closely related to sheep. 

There are over 300 distinct breeds of goat — one of the oldest domesticated species of animal. The archaeological evidence places their earliest domestication in Iran at 10,000 years ago.

Goat-herding is an ancient tradition that is still important in places like Egypt. Goats have been used for milk, meat, fur, and skins across much of the world. Milk from goats is often turned into white, crumbly goat cheese known as chèvre. If you love your palate, consider trying the Spanish take on slightly musty, velvety Garrotxa, a dense, aged explosion of flavour for the senses. You will taste some lemony tanginess with hints of toasted hazelnuts and aromatics of scrub brush and grasses growing in the foothills of the Pyrénées.

Female goats are referred to as does or nannies, intact males are called bucks or billies, and juvenile goats of both sexes are called kids. Castrated males are called wethers. While the words hircine and caprine both refer to anything having a goat-like quality, hircine is used most often to emphasize the distinct smell of domestic goats.
