Among plants, disaster floras precede stable plant communities such as forests.

Among animals, disaster faunas precede more stable faunas, which would normally contain a variety of specialized carnivores, herbivores, detritivores, insectivores, and piscivores, all of different sizes and occupying different ecological niches. What is meant by nutrient cycling? Why is that important? Nutrient cycling refers, in the marine realm, to the transfer of nutrients from the photic zone, in which photosynthesis-based primary production can take place, to the benthic zone, which cannot be accessed by sunlight and in which photosynthesis cannot take place.

Disruption of these nutrient cycles suggests an ocean that is fundamentally out of equilibrium. When was it?

Our best estimates of its age as of this writing suggest that it took place There were episodes of mountain-building in North America and Asia, there was a massive outpouring of flood basalts in India, and sea levels dropped to their lowest in the Cretaceous Period just before its end as the Cretaceous turned to the Tertiary, they had begun to rise again.

The greenhouse Earth of the mid-Cretaceous seems to have modulated some what towards more seasonality. And finally, the end of the Cretaceous was marked by the impact of an asteroid, estimated to be 10 km in diameter, into the Yucatan Peninsula in Mexico. What we know of the biotic extinctions suggests devastation not within our own experience. A major insect extinction has been reconstructed, Cambridge University Press, Dinosaurs: A Concise Natural History Topic Questions based upon the bite marks preserved in plant leaves!

Among fish, the extent of the extinction is largely unknown, but among amphibians and amphibious creatures such as crocodiles and turtles, extinction was not particularly significant. This contrasts markedly with the magnitude of the extinction among terrestrial tetrapods dinosaurs and mammals in which all dinosaurs went extinct, many, but obviously not all, birds went extinct including all those with teeth , and many mammals again, obviously not all went extinct.

In the marine realm, the extinction was equally impressive. The great nutrient cycles that characterized the Cretaceous oceans were disrupted, and there were major extinctions of planktonic microorganisms. Marine turtles also underwent a sizeable extinction.

Finally, pterosaurs all went extinct at the boundary. Our understanding of what went extinct, what didnt, and how quickly all that took place is hampered by the fact that the terrestrial vertebrate data, in particular, are limited to just a few localities in the western interior of North America.

The plant data are not much better, although at least other continents are represented. The record from the marine realm is far better, with many, many localities providing insights into the nature and rate of the extinction.

Describe the studies that concluded that the dinosaurs died abruptly. Three field-based studies have been carried out to determine the speed with which dinosaurs went extinct. In each of these three studies, the methods used were similar in some respects, but differed in others. Inductive reasoning is inherently uncertain. It only deals in the extent to which, given the premises, the conclusion is credible according to some theory of evidence. Examples include a many-valued logic , Dempster—Shafer theory , or probability theory with rules for inference such as Bayes' rule.

Unlike deductive reasoning, it does not rely on universals holding over a closed domain of discourse to draw conclusions, so it can be applicable even in cases of epistemic uncertainty technical issues with this may arise however; for example, the second axiom of probability is a closed-world assumption. An example of induction would be "B, C, and D are observed to be true therefore A might be true".

A is a reasonable explanation for B, C, and D being true. For example: A large enough asteroid impact would create a very large crater and cause a severe impact winter that could drive the non-avian dinosaurs to extinction. We observe that there is a very large crater in the Gulf of Mexico dating to very near the time of the extinction of the non-avian dinosaurs. Therefore, it is possible that this impact could explain why the non-avian dinosaurs became extinct. Note, however, that the asteroid explanation for the mass extinction is not necessarily correct.

Other events with the potential to affect global climate also coincide with the extinction of the non-avian dinosaurs. For example, the release of volcanic gases particularly sulfur dioxide during the formation of the Deccan Traps in India. Another example of an inductive argument: All biological life forms that we know of depend on liquid water to exist.

Therefore, if we discover a new biological life form it will probably depend on liquid water to exist. This argument could have been made every time a new biological life form was found, and would have been correct every time; however, it is still possible that in the future a biological life form not requiring liquid water could be discovered.

As a result, the argument may be stated less formally as: All biological life forms that we know of depend on liquid water to exist. All biological life probably depends on liquid water to exist. A classical example of an incorrect inductive argument was presented by John Vickers: All of the swans we have seen are white. Therefore, we know that all swans are white.


The correct conclusion would be: we expect all swans to be white. Any single assertion will answer to one of these two criteria. Another approach to the analysis of reasoning is that of modal logic , which deals with the distinction between the necessary and the possible in a way not concerned with probabilities among things deemed possible.

Rather, the premises of an inductive logical argument indicate some degree of support inductive probability for the conclusion but do not entail it; that is, they suggest truth but do not ensure it. In this manner, there is the possibility of moving from general statements to individual instances for example, statistical syllogisms, discussed below.

Note that the definition of inductive reasoning described here differs from mathematical induction , which, in fact, is a form of deductive reasoning. Mathematical induction is used to provide strict proofs of the properties of recursively defined sets.

Both mathematical induction and proof by exhaustion are examples of complete induction. Complete induction is a masked type of deductive reasoning. His method of inductivism required that minute and many-varied observations that uncovered the natural world's structure and causal relations needed to be coupled with enumerative induction in order to have knowledge beyond the present scope of experience. Inductivism therefore required enumerative induction as a component.

The empiricist David Hume 's stance found enumerative induction to have no rational, let alone logical, basis but instead induction was a custom of the mind and an everyday requirement to live.

While observations, such as the motion of the sun, could be coupled with the principle of the uniformity of nature to produce conclusions that seemed to be certain, the problem of induction arose from the fact that the uniformity of nature was not a logically valid principle. Hume was sceptical of the application of enumerative induction and reason to reach certainty about unobservables and especially the inference of causality from the fact that modifying an aspect of a relationship prevents or produces a particular outcome.


Awakened from "dogmatic slumber" by a German translation of Hume's work, Kant sought to explain the possibility of metaphysics. In , Kant's Critique of Pure Reason introduced rationalism as a path toward knowledge distinct from empiricism.

Kant sorted statements into two types. Analytic statements are true by virtue of the arrangement of their terms and meanings , thus analytic statements are tautologies , merely logical truths, true by necessity. Whereas synthetic statements hold meanings to refer to states of facts, contingencies. Finding it impossible to know objects as they truly are in themselves, however, Kant concluded that the philosopher's task should not be to try to peer behind the veil of appearance to view the noumena , but simply that of handling phenomena.

Reasoning that the mind must contain its own categories for organizing sense data , making experience of space and time possible, Kant concluded that the uniformity of nature was an a priori truth. Kant thus saved both metaphysics and Newton's law of universal gravitation , but as a consequence discarded scientific realism and developed transcendental idealism.

Usefully, features such as the method of chewing and biting are treated as single topics, with references to the differences between the groups. If you are in the same position, then this is a book for you as well as the undergraduates for whom it is written.

Some, living in the water column, are called planktonic, and others, living in the sediment at the bottom of the ocean, are called benthic see Figure The latest edition of Fastovsky and Weishampel's textbook provides an an accessible yet thorough introduction into subjects spanning biology and earth science, using dinosaur evolution as its guide.

I use it in my Dinosaurs class, and it is excellent AND affordable!
