HISTORICAL SKETCH OF THE FOSSIL ECHINOIDS FROM JAPAN
AND ADJACENT REGIONS
Although the number of fossil Echinoids hitherto described and illustrated from
Japan and the adjacent regions is small, yet there are several interesting and important
forms amongst them. Paleontological studies on the fossils from those regions are
considerably backward from the studies of the Recent forms, and it was probably
not later than the later half of the nineteenth century that the fossils from these
regions began to communicated by the scientists.
The species which have been described and illustrated from Japan and the adjacent
regions as fossil are given in the following list in the order of dates of publication,
together with their respective localities, geological ages, and original names.
1. The first work to make its appearance was a notice of Cidarid spines in the
description of the geology of Japan by two German authors: NAUMANN and NEUMAYR
(1890, pp. 1-45).
Cidaris cf. grandifera GOLDf'. Tosa, Cretaceous
Cidaris (new species) Tosa, Cretaceous
2. Several years later JIMBO (1894) described a Spatangoid from Hokkaido.
Ananchytidium sp. Hokkaido, Cretaceous
3. The important works of TOKUNAGA (formerly YOSHIWARA) began to appear
somewhat later, and the first paper on the fossil was entitled "On some Fossil
Echinoids of Japan" (1899).
Astriclypeus integris, n. sp. Kai, Miocene
Linthia nipponica, n. sp. Shinano, probably Pliocene
Schizaster recticanaiis, n. sp. Kaga, Pliocene
4. DE LORIOL described six fossil species from Japan in 1902.
Salenia (Pleurosalenia) haklzaidoensis, n. sp. Hokkaido, Tertiary
Ilarionia yoshiwarai, n. sp. Bonin Islands, Eocene
Echinolampas yoshiwarai, n. sp. Kazusa, Pliocene
