Bird fossils are rare because birds have hollow bones which are fragile and easily destroyed after their death. Additionally, birds are often scavenged by other animals soon after they die, further reducing the chances of their remains being preserved and fossilized. Finally, birds tend to live in environments that are not conducive to fossilization, such as forests or open water.

Are there bird excrement fossils?

Yes, they are called Fusulinids (Fusulinidae). They look like grains of rice.


Fossils of fungi are rare due to fungis?

Their composition of soft materials.


What type of fossil is bird tracks in snow?

Bird tracks in snow are not fossils, because snow melts and gets covered up by more snow, and so the bird that made them is probably still alive. (If it died shortly after and the tracks were still there, then they might be considered a trace fossil. ;))


What are examples of fossils?

Examples of fossils include preserved bones, teeth, shells, plants, and footprints. These remains provide evidence of past life forms and give insights into the Earth's history. Fossils can range from tiny microscopic organisms to large skeletons of dinosaurs.


Explain how fossils of birds similar to modern birds provide evidence of climates in the past.?

Fossils of birds similar to modern species offer insights into past climates by indicating the types of environments in which they thrived. For instance, the presence of certain bird fossils in specific geological layers can suggest whether an area was once tropical, temperate, or arid based on the ecological preferences of those birds. Additionally, these fossils can reveal information about the flora and fauna of the time, further informing scientists about the climate conditions that supported those ecosystems. Thus, studying these bird fossils helps reconstruct ancient climates and understand how they have changed over time.
