Euthria Cornea
''Euthria cornea'', common name : the spindle euthria, is a species of sea snail, a marine gastropod mollusk in the family (biology), family Buccinidae, the true whelks. Fossil reports The fossil record of this species dates back to the Miocene (age range: from 11.608 to 7.246 million years ago). These fossils have been found in Italy. Description The shell size of ''Euthria cornea'' varies between 20 mm and 80 mm. This mollusk has a robust fusiform shell, with a sharp apex. The opening is oval, wide, with slight striae. The horny operculum is oval. The coloration of the shell is quite variable, with irregular dark spots on a brownish-gray background. The mollusk is orange. This predatory species mainly feeds on small bivalves, opening slightly the valves with the strong foot and sucking the tissues. Distribution and habitat This species occurs in the Atlantic Ocean off Portugal and Morocco and in the Mediterranean Sea. It can be found at depths of 5 to 30 m, mainly on r ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. ...
