MUMMIFIED RED TILE FISH

An amazing mummified Red tilefish, Branchiostegus japonicus (Houttuyn, 1782) from Holocene deposits near Shizuoka, Japan. This specimen shows remarkable detail right down to the scales. Quite spectacular, truly.

Modern cousins of this 'horsehead' fishy fellow are native to the western Pacific ocean live as far south as the Arafura Sea today. They can grow to around 46 centimetres in length though most reach about 35 cm. Tilefish enjoy sandy and mud substrates and live in depths of 30 to 200 metres. Collection and photos from the deeply awesome Takashi Ito.

ANCIENT AEGEAN ELEPHANTS

The islands of the Aegean are peaks of underwater mountains that extend out from the mainland. 

Crete is the last of this range and boasts a diverse beauty from its high mountains of Psiloritis, Lefka Ori, and Dikti, to its ocean-caressed pink sand beaches.

Much of the island of Crete is Miocene and filled with fossil molluscs, bivalves, and gastropods who lived 5 to 23 million years ago in warm, tropical seas.

They are easily collected from their pink limestone matrix and are often eroded out, mixing with their modern relatives. Aside from the marine deposits, the island boasts some great vertebrate finds, including the remains of 

Deinotherium with its strange downward-curving tusks

Deinotherium giganteum, a massive 8 million-year-old mammal and primitive relative of the elephants roaming the Earth today. 

Deinotherium evolved from the slightly smaller, early Miocene, Prodeinotherium, though both genera were much larger than all of the more primitive proboscideans.

With an enormous large nasal opening at the centre of his skull, presumably, to house a rather largish trunk, Deinotherium may be the inspiration behind the myth of the Cyclops, the one-eyed giant from Homer's famous Odyssey. I'll share about some of the North African finds with you and you can judge for yourself. I think the resemblance is striking. 

The photo above is from the Grigore Antipa National Museum of Natural History in Bucharest, Romania. If you're in Romania, it's definitely a highlight.

PERICLIMENES COLEMANI

These lovelies are Coleman shrimp, Periclimenes colemani. They are generally found in mating pairs atop the exquisitely beautiful but frightfully poisonous, Fire Sea Urchin, Asthenosoma varium.

The female of the Coleman pair in this photo is the slightly larger beauty on the left. She's looking poised and ready to catch something tasty with her open claws. Coleman shrimp and several other fish and invertebrates were named after the Australian naturalist and underwater nature photographer, Neville Coleman. It was his life's mission to document all of the sea life of Australia.

CERATIOCARIS OF SCOTLAND

This braw fellow is Ceratiocaris papilio (Salter in Murchison, 1859) a Pod Shrimp from the Silurian mudstones of the Kip Burn Formation in the Midland Valley of Scotland. 

He swam in our ancient seas, rising with the tide alongside and in the waters above many marine creatures that you will likely know — crinoids, brachiopods, trilobites and new and exotic fish — some sporting jaws for the first time in their lineage.

Ceratiocaris is a genus of extinct Palaeozoic phyllocarid crustacean whose fossils are found in marine strata from the Upper Ordovician through to the Silurian.

They are typified by eight short thoracic segments, seven longer abdominal somites and an elongated pretelson somite. Their carapace is slightly oval-shaped; they have many ridges parallel to the ventral margin and possess a horn at the anterior end.

This tidy specimen is from the Silurian mudstones that characterize the Kip Burn Formation with its dark laminated silty bands. The lower part of the Kip Burn houses the highly fossiliferous ‘Ceratiocaris beds’, that yield the arthropods Ceratiocaris, Dictyocaris, Pterygotus, Slimonia and the fish Birkenia and Thelodus.

The upper part of the formation, the Pterygotus beds, contain abundant eurypterid fauna together with the brachiopods Lingula and Ceratiocaris. The faunas in the Kip Burn Formation reflect the start of the transition from marine to quasi- or non-marine conditions in the group. Ceratiocaris is also well-known from the Silurian Eramosa Formation of Ontario, Canada, which also has rather nice eurypterids, too. Photo credit/collection of York Yuxi Wang and Tianyi Zhang.
