This presentation simultaneously resurrects ruins and bones and fossilizes our own technological path.

In these rare cases when organic tissue fossilizes, minerals come in to replace the tissue.

"I felt that a tradition must be nourished with new material, otherwise it fossilizes," he told the British newspaper The Telegraph in 2012.

Dinosaur senses are difficult subjects of study for paleontologists since soft tissue anatomy rarely fossilizes.

Fossilization occurs often in adult language learners. It can also occur when a learner succeeds in conveying messages with their current L2 knowledge. The need to correct the form/structure is therefore not present. The learner fossilizes the form instead of correcting it.

Radular teeth of the squid Illex illecebrosus Most cephalopods possess a radula as well as a horny chitinous beak, although it is reduced in octopuses and absent in Spirula. The cephalopod radula rarely fossilizes: it has been found in around one in five ammonite genera, and is rarer still in non-ammonoid forms. Indeed, it is known from only three non- ammonoid taxa in the Palaeozoic era: Michelinoceras, Paleocadmus, and an unnamed species from the Soom Shale.

A fossil hash Hash fossils are not actually one fossil, they are many fossils in the same rock. The term hash fossil describes the fossil formed when all the organic material in an environment falls to the ocean floor and fossilizes, hence the name "hash". When you look at a hash fossil, you actually are looking at a piece of ancient seabed. In hash fossils you can usually find the pieces of corals, crinoids, bryzoans, and brachiopods.

Quickly-perishable foods, and those not grown at a commercial scale, such as fruits, nuts, and vegetables are underrepresented in historical records, but archeological evidence suggests such foods were nonetheless important seasonal supplements to the Irish diet. As evidence suggests most urban dwellings were furnished with gardens, the growth and harvest of a variety of fresh fruits, herbs, and vegetables would have provided variety of the diets of urban dwellers. As well, as fragile plant life erodes and disappears quickly compared to grain chaff that fossilizes easily, what evidence is recovered may present a distorted assessment of what ratio of cereals to plant life was consumed at the time only because there is no empirical data of such eroded materials.Tierney, J., & Hannon, M. (1986).

Directly related to the quantitative nature of the planning process is the lack of innovation, which Rutland identifies as one of the most critical weaknesses of the Soviet economy. Opportunity costs that would be easily identified in a free market tend to go unnoticed in the Soviet economy for a number of reasons, most importantly a)the planners' distance (geographically, temporally, hierarchically, etc.) from the actual site of production and b)the very essence of the planning process, whose objectives tend to be set from what has come to be called 'the achieved level'. In other words, the central planners, having no clear idea of where to go with the economy, opt for the most obvious route of blunt economic growth: the outputs that were achieved in the previous plan are obviously within the economy's limits, and with some increase in inputs (and perhaps additional pressure on plant managers), these outputs can be slightly increased. While this planning strategy has served to make the USSR a powerhouse in the production of commodities such as steel and chemicals, it inevitably fossilizes the production process and retards technological progress.
