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.

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

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)

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.
