Fossil record.
As the fossil record becomes more complete, the pattern will emerge as to which condylarth is ancestral to archaeocetes and which archaeocete is ancestral to living cetaceans. The first fossil cetacean, Pakicetus, is known from the Early Eocene Epoch (55.8 million to 49 million years ago) in Pakistan. It has recently become clear that ...

What is the fossil record? The fossil record refers to all the fossils that we know from the rocks around us. ‘It goes from when we get the first single-celled organisms, all the way through to the ancestors of humans today and Ice Age mammals,’ explains Paul. ‘The fossil record tells us what plants and animals were around at different ... Aug 17, 2016 ... If the rock layers are undisturbed, the deepest layers are the oldest and layers near the surface are the youngest, shown in Figure below. The Fossil Record The claim that fossils document evolution is simply not true. ICR geologist Dr. John Morris and zoologist Frank Sherwin unearth the evidence of earth’s history and conclude that the fossil record is incompatible with evolution, but remarkably consistent with the biblical account of creation and the great Flood of Noah’s day.
The fossil record is not, alas, complete or unbroken: most organisms never fossilize, and even the organisms that do fossilize are rarely found by humans. Still, the fossils we have been lucky enough to find offer unique insights into evolution over long timescales.

The fossil record reveals how horses evolved. The lineage that led to modern horses (Equus) grew taller over time (from the 0.4 m Hyracotherium in early Eocene to the 1.6 m Equus). This lineage also developed longer molar teeth and the degeneration of the outer phalanges on the feet. Fossils are a window into the past.
That's called the fossil record. Paleontologists have been collecting fossils from sedimentary rock layers around the world for over two hundred years. Their goal is to figure out the succession of species through all of geologic time. Once that succession is known, it serves as a scale of geologic time. Then, if you find a particular fossil in ...

The geologic time scale or geological time scale ( GTS) is a representation of time based on the rock record of Earth.

It is a member of the Protostegidae, a likely sister group of modern leatherback sea turtles.The use of temporal information from the fossil record as data in phylogenetic inference has been criticised however, with concerns ranging from the incompleteness of the geological record to the non-clocklike evolution of morphology . Inferring the phylogenetic position of fossils can only be achieved using morphological …The fossil record is as much a document of clade failure as success, and provides a direct observational window on a wide range of natural experiments, in deep time and directly preceding the present biological moment. At the same time, another key finding from the fossil record is a lack of extinction where it might be expected.
