How many missing links have been found in evolution?
All fossil found to date were missing link. Missing link is a non-scientific term describe new found transitional fossil. Any single fossil found and placed along the line of evolution would yield 2 new missing link mathematically.
What is a fossil evidence of?
A fossil is evidence of a once living animal. A fossil is created when an animal dies in a mud or other soft dirt or sediment. Over time, the animal will decompose and leave the bones. Over time, these bones will get covered by dirt, rocks water, etc. After a couple thousand years the bones will get compressed into sediment, waiting to be discovered. Something similar to a fossil is and imprint. This is where an impression of a plant or animal is pushed into a soft sediment and hardens.
Trilobites are an example of?
Trilobites (meaning "three lobes") are a well-known fossil group of extinct marine arthropods that form the class Trilobita. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (526 million years ago) and flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Devonian, all trilobite orders, with the sole exception of Proetida, died out. Trilobites finally disappeared in the mass extinction at the end of the Permian about 250 million years ago.When trilobites first appeared in the fossil record they were already highly diverse and geographically dispersed. Because trilobites had wide diversity and an easily fossilized exoskeleton an extensive fossil record was left, with some 17,000 known species spanning Paleozoic time.A Trilobite is a fossil. The fossilised remains of a type of animal called an arthropod that lived in the sea between 521 and 250 million years ago. They are now extinct.They are called "trilobites" because their body shapes have 3 lobes. They looked a bot like woodlice.I have made a link to a picture of a trilobite below.
A quote by Stephen Jay Gould?
We pass through this nice world, but once. For many more see the related link for more. As a paleontologist by profession this was evolutionist Stephen Jay Gould's area of expertise. Although revered as a great scientist Gould has received some criticism from fellow believers in evolution for his candid comments about the nature of the fossil record. He referred to the fossil record in relation to evolution in the following way:"The absence of fossil evidence for intermediary stages between major transitions in organic design, indeed our inability, even in our imagination, to construct functional intermediates in many cases, has been a persistent and nagging problem for gradualistic accounts of evolution."Stephen Jay Gould (Professor of Geology and Paleontology, Harvard University), 'Is a new and general theory of evolution emerging?' Paleobiology, vol.6(1), January 1980,p. 127."All paleontologists know that the fossil record contains precious little in the way of intermediate forms; transitions between the major groups are characteristically abrupt."Stephen Jay Gould 'The return of hopeful monsters'. Natural History, vol. LXXXVI(6), June-July 1977, p. 24."The extreme rarity of transitional forms in the fossil record persists as the trade secret of paleontology. The evolutionary trees that adorn our textbooks have data only at the tips and nodes of their branches; the rest is inference, however reasonable, not the evidence of fossils. Yet Darwin was so wedded to gradualism that he wagered his entire theory on a denial of this literal record:The geological record is (here Gould is quoting Darwin) extremely imperfect and this fact will to a large extent explain why we do not find intermediate varieties, connecting together all the extinct and existing forms of life by the finest graduated steps. He who rejects these views on the nature of the geological record will rightly reject my whole theory. (end of quote)Darwin's argument still persists as the favored escape of most paleontologists from the embarrassment of a record that seems to show so little of evolution. In exposing its cultural and methodological roots, I wish in no way to impugn the potential validity of gradualism (for all general views have similar roots). I wish only to point out that it was never "seen" in the rocks.Paleontologists have paid an exorbitant price for Darwin's argument. We fancy ourselves as the only true students of life's history, yet to preserve our favored account of evolution by natural selection we view our data as so bad that we never see the very process we profess to study."Stephen Jay Gould 'Evolution's erratic pace'. Natural History, vol. LXXXVI95), May 1977, p.14.Gould's commitment to Darwinian evolution would not allow him to abandon it. However what the evidence shows is clear from these statements of Gould, no matter what he makes of them.
Dot diagrams are used to represent?
A dot diagram (also called an Electron Dot Diagram, and a Lewis Structure) is a way to show the valence electrons that surround an element. See related link for a good lesson on how to make a dot diagram.
Were do you find pictures of ferns you can print?
See link provided below for a photo gallery that has pages of pictures of ferns that you can print out.
Any precambrian tine animals and plants that have turned into fossils?
Yes, although the fossil record for the precambrian period is scarce. See related link.
Would it make a cow sick if it ate ferns?
Yes, see the link on bracken poisoning.
What is the scientific name for missing link?
There is no specific scientific name for the concept of the "missing link" in human evolution. It is a colloquial term that has been used in the past to describe hypothetical transitional forms in the evolutionary lineage of humans. Scientists now understand that evolution is a complex and continuous process with many transitional forms, rather than a single missing link.

How tall does an ostrich fern grow?
Some species of ferns can reach as tall as 20 meters high. Most ferns will grow roughly 10 meters high depending on their species and what the area is around them.
