Question: Which fossil is the youngest?

This cranium, dated to around 139-124 million years ago, is the youngest known specimen of a haramiyid and suggests that the species persisted in the northern continents after the breakup of Pangaea. Haramiyids represent an enigmatic group of mammals known from the Triassic and early Jurassic periods.

Which fossil is most likely the youngest?

The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently). A fossil is the remains or traces of plants and animals that lived long ago.

How can you tell which fossil is oldest and which is youngest?

The oldest layers are on the bottom, and the youngest layers are on the top. Because sediments sometimes include once-living organisms, sedimentary rock often contains a lot of fossils.

Where was the youngest fossil found?

A dinosaur fossil believed to be the youngest ever found was discovered by Yale scientists in Montanas Hell Creek formation, a study published in Biology Letters revealed.

How can you tell which fossil is the oldest?

To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
