But fossil records
from this time are spotty, with only small fragments identified.
from New Zealand, Japan, Europe and North America, all showed evidence of mass deforestation.
Fossils in Namibia, meanwhile, represent the Ediacarian biotope, the earliest discovered marine ecosystem, dating back 600 million years and made up entirely of strange, pneumatic creatures that floated.The rise of fish, too, is well represented in Africa's fossil records
However, these fossil records
have their limitations - ones that need to be properly understood in order to correct for sampling biases.
Examination of fossil records
by scientists from the University of Bath determined that the asteroid's impact had been much more severe than previously thought.
According to a report by BBC News, scientists used fossil records
stretching back 540 million years to work out the evolution rate at reefs.
Previously, some scientists had assumed that the fossil records
of all of those groups of species would show a large number of Lazarus taxa, says Fraiser.
"From fossil records
to the irreducible complexity of biochemistry, the logical and evidential fallacies of evolutionary theory are exposed."
Dragonflies are among the most ancient of living creatures, with fossil records
dating back 300 million years, predating dinosaurs by over 100 million years and birds by some 150 million, according to the World Dragonfly Association.
The board voted 13-2 July 12 against proposed changes that would have required students to "analyze the impact of new scientific facts on the theory of evolution" and to "analyze evidence of fossil records
, similarities in body structures, embryological studies and DNA studies that support or do not support the theory of evolution."
Only when they began to compare the plant's leaf structure to fossil records
were the scientists able to determine that what Mogul had stumbled onto was a tree thought to be extinct since the age of the dinosaurs.
"Previous fossil records
suggested this group was part of an ancient lineage from North America but the DNA showed these unusual forms were part of the modern radiation of equid species," Orlando said.
