If there are enough helpers some may be taken on minifieldtrips along the shore to look for bone bed or better fossils, and have the geology explained better.

If the loss of a dental element is already bad, an immediate implant is even worse because the bone bed has already been milled, and failure in the osseointegration process results in a rapid formation of granulation tissue; alteration of local irrigation; formation of areas of necrosis, in short, a severe collapse of the peri-implant tissues with increased bone remodeling; and alteration in the vestibular gingival margin, compromising the esthetic result of the procedure [5, 6].

Through 13 essays (some based on papers from the 2011 Plains Conference held in Tucson, Arizona), anthropologists, archaeologists, and other researchers from the US and Mexico explore the Plainview Paleoindian artifact style, considering the nature of the original Plainview bone bed in northwest Texas and its stratigraphic context; the age of the Plainview bison kill and the age range of the Plainview type; and what constitutes the Plainview type, how widespread it is, and how it is related to other Paleoindian artifact styles like Folsom and Goshen.

Given the required target accuracy and the minimal invasion, a registration method, which was the joint registration of the bone bed malleus short process, was employed in this study.

Geochemical interpretations of the fossil record are further explored by Fadel et al., revealing palaeoenvironmental signatures from the rare earth element compositions in vertebrate microremains of the Upper Wenlock Vesiku Bone Bed from Saaremaa Island in Estonia.

Paulo Manzig from Universidade do Contestado, Brazil, and colleagues discovered the bones in a pterosaur bone bed in rocks from the Cretaceous period.

Although fossil Carcharodon (Linnaeus, 1758) teeth form a remarkable "bone bed" that concentrated on the Miocene seafloor over about a half million years at Shark Tooth Hill near Bakersfield, only a few isolated reports of lamnid shark teeth have been reported from Miocene Puente Formation in the Los Angeles Basin.

In order to obtain a firm bone bed for the placement of the acetabular cage, the structural bones should be fixated by screws and the granular bones should be packed by SLooff-Ling techniques.18
