Late Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clypeaster Japonicus
''Clypeaster japonicus'', the Japanese sea biscuit, is a species of sea urchin in the Family Clypeasteridae. This species was first scientifically described in 1885 by the German zoologist Ludwig Heinrich Philipp Döderlein. Description This is a large species with a strong test, growing to a maximum length of around . In shape it is an elongated pentagon, the aboral (upper) surface slightly higher at the apex than at the margins. The length of the petaloid area amounts to two thirds or more of the total length of the test. The anterior petal is open distally while the two posterior, paired petals are closed distally. The oral (under) surface is fairly flat, but deeply concave around the mouth, with conspicuous, but short, indented food grooves. The anus is on the oral surface near the posterior margin. The primary spines are rather longer than the densely felted secondary spines. When alive, this species is a uniform brown colour apart from the petals, which are a darker brown. ...

Clypeaster Humilis
''Clypeaster humilis'' is a species of sea urchin in the Family Clypeasteridae. This species was first scientifically described in 1778 by the German biologist Nathanael Gottfried Leske. It occurs in the tropical Indo-Pacific region. Description ''Clypeaster humilis'' is a medium-sized species of sea biscuit, growing to a maximum length of . Its shape is pentagonal and it is slightly longer than it is broad. The margin is quite thick and the petaloid area is raised above the rest of the surface. The individual petals are closed and the petaloid area occupies less than half the width of the test. The oral (under) surface is somewhat concave and the food grooves are long and deeply incised. The spines are short, with the primaries hardly exceeding the length of the secondaries. When living, this sea biscuit is greenish-grey or brownish, the petaloid area sometimes being darker brown; the bare test is yellowish or beige.
