United States: Numerous animals are at brinks of extinctions whilst disappearing at times of ongoing 6th mass extinction events with no leaving forth any fossil’s permanent records. It is revealed by newer study. Whilst comparisons conducted with biodiversity current crisis, known often as “sixth extinction” along with that of geological pasts needing data equivalent. It is told by Roy Plotnick, professor at University of Illinois at Chicago.
Contrast and compare: Scientist compared “Red List” of species endangered with many databases ecologically of species living and 3 paleontological database of fossils catalogued. It is indicated by analysis statistical that most threatened species having most disappearing likeliness lack records of fossils (85 percent).
Matters of sizes: Body sizes are obvious factors. Big things leave fossil records. 3 percent of present day’s bird’s species threatened and 1.6 percent of reptile species threatened have known records of fossils. Extinctions of ancient era are underestimated: Palaeontologist contemporary need to not consider old age’s marine hard-shelled invertebrates’ fossil records.
Betting on reliabilities: Fossils nevertheless, provide reliable record of life only on earth for posterity. For forthcoming generations fossil records play an important role. A fossil trace stands tests of time duration: Fossil traces have more durability’s tan human records. But present days’ species of vertebrates and invertebrates do not have fossil traces or fossil records.
