Fossilized bioelectric wire – the trace fossil Trichichnus [PDF]

open access: yesBiogeosciences, 2014
Abstract. The trace fossil Trichichnus is proposed as an indicator of fossil bioelectric bacterial activity at the oxic–anoxic interface zone of marine sediments. This fulfils the idea that such processes, commonly found in the modern realm, should be also present in the geological past.

Fossil–Lagerstätten [PDF]

open access: yesGeology Today, 2008
Possibly every palaeontologist, before and after Charles Darwin, has been well aware that the fossil record is very incomplete. Only a tiny percentage of the plants and animals alive at any one time in the past get preserved as fossils, both in terms of numbers of individuals and in terms of numbers of species.

Map of fossil resins of Ukraine

open access: yesМінеральні ресурси України, 2020
Finding out the conditions of the geological past under which tar secretions were fossilised and primary bio-sedimentary deposits of protoamber were accumulated and amber-succinite placers formed in the marine environment is an important link in ...

First Language Influence and Fossilization in Second Language Vocabulary Acquisition

open access: yesStudies in Applied Linguistics & TESOL, 2009
While a considerable amount of second language acquisition (SLA) research has focused on the acquisition process itself, another strand of research has specialized in investigating the fossilization of specific linguistic features. Han’s (2009) Selective

Are Grammatical Morphemes Hard or Soft?

open access: yesWorking Papers in Applied Linguistics and TESOL, 2015
For the past few decades, one of the most persistent criticisms against second language acquisition (SLA) research has been the derivative nature of its origin in establishing its theoretical and methodological foundation.

Hypergene alterations of succinite and its vulnerability under various environmental conditions

open access: yesGeo&Bio, 2021
The article describes the alteration of succinite under conditions of hypergenesis as a result of oxidation, including a change in colour, contraction of the outer surface and the appearance of microcracks, changes in the construction of the outer ...

FOSSILIZATION, COMMUNICATIVE RATIONALITY AND COMMUNICATION STRATEGIES IN SECOND LANGUAGE LEARNING

open access: yesRUDN Journal of Language Studies, Semiotics and Semantics, 2019
Fossilization was first defined in 1972 as a failure, or an ultimate attainment in adult second language acquisition that falls short of native-speaker competence. It represents a final stage in the interlanguage development of the individual learner and

Taphonomic experiments imply a possible link between the evolution of multicellularity and the fossilization potential of soft‐bodied organisms

open access: yesEcology and Evolution, 2021
The reliability of evolutionary reconstructions based on the fossil record critically depends on our knowledge of the factors affecting the fossilization of soft‐bodied organisms.

Experimental Aqueous Alteration of Cortical Bone Microarchitecture Analyzed by Quantitative Micro-Computed Tomography

open access: yesFrontiers in Earth Science, 2021
Bones are one of the most common vertebrate fossil remains and are widely used as proxy archives in palaeontology and archaeology. Previous histological analyses have shown that bone microarchitecture is mostly well-preserved in fossil remains, but ...

Written Corrective Feedback as a Means to Validate the Selective Fossilization Hypothesis: Issues to Consider

open access: yesStudies in Applied Linguistics & TESOL, 2009
Since Selinker (1972) coined the term fossilization to characterize the phenomenon in which second language (L2) learners cease to progress in the acquisition process, much effort (e.g., Bates & MacWhinney, 1981; Krashen, 1981, cited in Han & Odlin, 2006)
