In 1971 I released a assessment of ichnology different concentrating basically on strains made (Houston AAPG: SEPM hint Fossil box by means of a definite staff of organisms, regardless journey Guidebook) that i presumed may be in their environment. however, unnecessary re­ dundancy has expectantly been eradicated. elevated relatively simply right into a useful a number of the chapters are extra precise­ booklet at the topic. I probed that possi­ ized than others (because of the character of bility for your time, pondering that i'd specific topics); for this reason, those should be write the e-book myself. As i started to out­ a little bit much less popular or "comprehensible" line the chapters in additional aspect, despite the fact that, than others-depending upon the reader's it quickly turned obvious that my own personal pursuits and history. different dif­ wisdom of too many elements of ichnology ferences within the scope and content material of vari­ scraped backside all too quickly.

One of these (Fig. 8A) is a branched structure strongly resembling the pattern of bifurcation seen in burrow systems of shallowwater thalassinideans and similar shrimp. The walls are not thickly lined, but the character of the sediment fill suggests an abandoned dwelling burrow. Equally significant is a type of dwelling burrow having walls as thick as 3 mm (Fig. 8B); the overall burrow is vermiform, about 10 mm in diameter, and oriented predominantly horizontally. Deep-sea benthos are mostly deposit feeders and therefore do not ordinarily expend much energy in maintaining permanent domiciles; the above burrows represent obvious and important exceptions, however, reflecting behavioral responses to environmental conditions other than simply the depth of water or distance from shore.

CONCLUSIONS The study of trace fossils involves several concepts and approaches that are somewhat unusual among other branches of geology and biology, perhaps imparting a "mystical" Robert W. Frey 36 or esoteric quality to the research. But mysticism is merely a synonym of "unfamiliar," and in this and the following chapters we hope to dispel a great deal of the unfamiliarity and to show how ichnology is rapidly becoming a mature, wellfounded subdiscipline, an integral part of the geological and biological sciences.
