There are many groups of plants in the fossil record for which there are no living species today.
Surface fouling has little chance of being preserved in the fossil record because it is merely an accumulation of mud on the surface of the shell, and will not be addressed further in this study.
But without the fossil record, we really have no scale to measure the significance of the impact we are having.
The fossil record compiled by Prideaux and his colleagues shows that "the mammal fauna was resilient through time, despite climate fluctuations," says David W.
Shanan Peters, an assistant professor of geoscience at the University of Wisconsin-Madison said fossil record could tell us a great deal about the true history and drivers of biodiversity on Earth.
More-recent gaps in the fossil record at most sites in the area--one between 5,000 and 4,000 years ago, and another between 2,000 and 1,100 years ago--indicate periods when ocean conditions weren't favorable for penguin breeding and the climate was substantially cooler than it is now, the researchers speculate.
Researchers from the University of Chicago, West Virginia University, and The Ohio State University found that the mass extinction known as the Hangenberg event produced a "natural experiment" in the fossil record with results that mirror modern observations about predator-prey relationships.
The fossil record contains examples of species changing and diverging into new species (snails).
The fossil record shows evidence of rapid burial on a global scale.
In addition, course material propping up two longtime creationist canards--that evolution violates the third law of thermodynamics and that the fossil record backs creationism--were eliminated.
While punctuated equilibrium (PE) reflected in the fossil record is a strong negative evidence to the underlying principle of phyletic gradualism (PG) enshrined in the evolutionary theory, the phenomenon of cell-directed mutagenesis challenges another tenet of the theory, namely, the requirement of stochastic mutations produced by extra-cellular agents to create heritable changes in the organism.
But Liaoning has provided us with a fantastically diverse fossil record that includes fossils of plants and invertebrates [animals without a backbone] such as crayfish, dragonflies, and fly-like creatures.
