Fossils space the preserved remains, or traces that remains, of ancient organisms. Fossils room not the remains of the biology itself! They are rocks.

You are watching: Which of the following is least likely to be preserved as a fossil?


A fossil deserve to preserve whole organism or just component of one. Bones, shells, feathers, and also leaves deserve to all come to be fossils.
Fossils deserve to be very huge or really small. Microfossils are just visible with a microscope. Bacteria and pollen room microfossils. Macrofossils can be number of meters long and weigh several tons. Macrofossils deserve to be petrified trees or dinosaur bones.
Preserved remains become fossils if they reach period of around 10,000 years. Fossils can come indigenous the Archaeaean Eon (which began almost 4 billion year ago) all the means up to the Holocene date (which proceeds today). The fossilized teeth of wooly mammoths are several of our most "recent" fossils. Few of the oldest fossils room those of old algae that resided in the ocean more than 3 billion years ago.
The native fossil originates from the Latin word fossus, an interpretation "having to be dug up." Fossils are often uncovered in rock formations deep in the earth.
Fossilization is the process of remains ending up being fossils. Fossilization is rare. Many organisms decompose fairly quickly after castle die.
For an biology to it is in fossilized, the remains usually need to be spanned by sediment quickly after death. Sediment can incorporate the sandy seafloor, lava, and also even difficult tar.
Over time, mineral in the sediment seep right into the remains. The remains become fossilized. Fossilization usually take place in organisms v hard, bony body parts, such as skeletons, teeth, or shells. Soft-bodied organisms, such as worms, are seldom fossilized.
Sometimes, however, the sticky resin that a tree can become fossilized. This is referred to as fossilized resin or amber. Amber can preserve the body of many delicate, soft-bodied organisms, such together ants, flies, and mosquitoes.
The fossils that bones, teeth, and shells are referred to as body fossils. Most dinosaur fossils space collections of body fossils.
Trace fossils space rocks that have actually preserved evidence of organic activity. They room not fossilized remains, just the traces of organisms. The imprint of an ancient leaf or footprint is a trace fossil. Burrows can additionally create impressions in soft rocks or mud, leaving a trace fossil.
Paleontologists are world who examine fossils. Paleontologists find and study fossils anywhere the world, in virtually every environment, from the hot desert to the humid jungle. Studying fossils help them learn about when and how different species lived millions of years ago. Sometimes, fossils phone call scientists just how the earth has changed.
Fossils of ancient marine animals called ammonites have been uncovered in the highest mountain range in the world, the Himalayas in Nepal. This tells scientists that millions of years ago, the rocks that became the Himalayas to be at the bottom of the ocean.
Fossils of an old giant shark, a megalodon, have actually been found in the landlocked U.S. State the Utah. This tells researchers that numerous years ago, the center of north America was probably totally underwater.

Mary AnningThe 19th-century brother fossil collector mar Anning showed you don"t have to be a paleontologist to contribute to science. Anning was among the an initial people come collect, display, and correctly identify the fossils the ichthyosaurs, plesiosaurs, and pterosaurs. Her contributions come the knowledge of Jurassic life to be so exceptional that in 2010, Anning to be named among the ten British ladies who have actually most affected the history of science.


MicrofossilsEven though many of us have only viewed dinosaur fossils in museums, many fossils space not the big. Some of them room so small, girlfriend can"t check out them there is no a microscope.


translucent, yellow-orange material made that the resin of old trees. Amber is sometimes considered a gemstone.


one of many extinct species of big animals concerned elephants, with long, bent tusks. The last mammoths ended up being extinct around 5,000 years ago.


fossil that can only be seen and also analyzed v a microscope, such together a serial of pollen or a single bacterium.


powdery material developed by plants, every grain the which has a male gamete capable of fertilizing a woman ovule.

preserved proof of the existence or behavior of an ancient organism, such together tracks, feces, or burrows.
