Kotake, Nobuhiro 1989 07 15: Paleoecology of the Zoophycos producers.Lethaia, Vol. 22. pp. 327-341.Oslo. ISSN 0024-1164. Well‐preserved Zoophycos and Spirophyton‐like burrows occur in the Upper Pliocene deep‐sea sediments exposed along the southern coast of Boso Peninsula, central Japan.They consist of an axial tunnel and helically coiled spreite with fecal pellets.

The feeding mechanism of Zoophycos producers demonstrates non-selection by particle size or quality. The characteristic morphology and mode of Occurrence of Zoophycos and the presence of pellets with pyroclastic grains imply that the Zoophycos producers were surface deposit-feeders. They dwelt in a burrow within the sediment and ingested the grains with nutrient detritus on the sea floor ...

smaller than Zoophycos, the broad morpho-logic similarity indicates that the two ichno-genera reflect generally similar behavior. The paleoenvironmental distribution of Zoophycos has been studied extensively. Orig-inally, Seilacher (1967) considered flat simple forms of Zoophycos indicative of intermediate water depth and more complex forms char-Zoomastigota (Zoomastigina) A phylum of the Protoctista containing heterotrophic protozoa that can be parasitic or free-living.They possess one or more undulipodia (flagella) for locomotion.

The Amuri Zoophycos represents a complex spreite of spreites (= spreiten), which consists of a spiralled set of numerous, overlapping, protrusive, Rhizocorallium‐like spreite tongues. These tongues are repetitive excavations produced by an infaunal deposit feeder probing progressively downward and outward in the sediment.Zoophycus 5.12c YDS 7b+ French 27 Ewbanks IX- UIAA 27 ZA E6 6b British Avg: 3 from 1 vote Routes in 3.

ZOOSThough modern zoos are usually traced to Paris and London in the 1700s, it is difficult to determine exactly when the collecting and cataloging of "exotic" animals began. Certainly the ancient Egyptians, the Greeks, the Mesopotamians, the Indians, the Chinese, and the Romans all had animal collections that were displayed in various ways to selected persons.The Zoophycos structures illustrated in Fig. 2 resemble sections of "Banderkreide" from the Maastrichtian of north-westGermany (Yoigt and Hantzschel, 1956, pI. 15); the tty" structures from the Permian of Western Canada (McGugan, 1963, pI. 1, figs. 3-12);and the horizontal Zoophycos septa from the Lower Devonian of Maryland, U.S.A.
