What kind of fossils can tell scientists what dinosaurs ate?
Answer 1: Coprolites or fossil “poop” are one way that paleontologists (scientists who study ancient life other than humans) try to understand what dinosaurs and other fossil animals ate when they were living but as you can imagine it’s not always so easy to tell who made the coprolites.
Which is an example of Earth’s condition slowly changing?
Some changes are due to slow processes such as erosion and weathering and some changes are due to rapid processes such as landslides volcanic eruptions and earthquakes.
What are traces of living things that are preserved in rock called?
Do insects feel pain?
Over 15 years ago researchers found that insects and fruit flies in particular feel something akin to acute pain called “nociception.” When they encounter extreme heat cold or physically harmful stimuli they react much in the same way humans react to pain.
Are any bugs extinct?
As of July 2016 the International Union for Conservation of Nature (IUCN) lists 58 extinct species 46 possibly extinct species and one extinct in the wild species of insect.
How do scientists know about dinosaurs?
How do we know what dinosaurs and other extinct animals ate?
What can be used to determine what ancient creatures ate?
When scientists want to know what our ancient ancestors ate they can look at a few things: fossilized animal bones with marks from tools used to butcher and cut them fossilized poop and teeth. The first two can tell us a lot but they’re hard to come by in the fossil record.
How fossils are preserved in sedimentary rocks?
Minerals And Rocks. … Fossils in the form of leaves of plants insects or some bovine animals and pieces of bones shells or some hard parts of old living beings are deposited into the layers of the sedimentary rocks. In this way fossils are preserved in sedimentary rocks.
Which type of rock commonly contains fossils?
In which type of rock would you typically find fossils?
Can insects get drunk?
But what about insects? Insects may seem too small in size to become drunk off of alcohol but you would be wrong. Just about any insect can become intoxicated if you expose it to alcohol. However there is at least one type of insect that actively seeks out fermented fruit that causes intoxication.
Do insects bleed?
In insects blood is used to carry nutrients throughout their bodies but not oxygen. Oxygen comes through a system of air tubes that connect to the outside through openings called spiracles. Insects do bleed when they are hurt and their blood clots like a human’s so a minor wound will usually heal.
What if we killed all mosquitoes?
If mosquitoes were eradicated from the planet hundreds of species of fish would have to change their diet. … Without these fish the food chain would be disrupted in both directions. Some species of bird bat spider insect salamander lizard and frog also eat mosquitoes and may struggle without them.
Did flies exist with dinosaurs?
As ancient dinosaurs evolved the ability to fly eventually becoming modern birds they put a cap on insect size through predation and competition.
Do Dragonflies eat?
Are flies extinct?
The answer is no. Don’t count on it to happen because flies are likely to outlive us. They’re fast to reproduce and they surpass us when it comes to evading physical attacks (try swatting them).
Are dinosaurs still alive in 2021?
In an evolutionary sense birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds however there is no scientific evidence that any dinosaurs such as Tyrannosaurus Velociraptor Apatosaurus Stegosaurus or Triceratops are still alive.
Can dinosaurs come back?
The answer is YES. In fact they will return to the face of the earth in 2050. We found a pregnant T. rex fossil and had DNA in it this is rare and this helps scientists take a step closer of animal cloning a Tyrannosaurus rex and other dinosaurs.
What dinosaurs had 500 teeth?
Nigersaurus
This bizarre long-necked dinosaur is characterized by its unusually broad straight-edged muzzle tipped with more than 500 replaceable teeth. The original fossil skull of Nigersaurus is one of the first dinosaur skulls to be digitally reconstructed from CT scans.
What can fossils of teeth tell us about extinct animals?
To understand what extinct animals such as dinosaurs ate we can compare their tooth types to the range of tooth types that we see with modern animals such as these carnivorous and omnivorous animals. … These kinds of clues tell us that this animal was a meat eating animal. This fossil is the jaw of a Hadrosaur.
How do scientists know dinosaurs were reptiles?
Short answer: Dinosaurs are reptiles because their ancestral lineage puts them into the reptile family. It’s a little tricky to define “reptiles” today. Many biologists have moved to defining groups by clades which can be simplified as groups of descendants from common ancestors.
How do paleontologists use fossils as clues for dinosaur habits?
Paleontologists use fossil remains to understand different aspects of extinct and living organisms. Individual fossils may contain information about an organism’s life and environment. … Some fossils show how an organism lived. Amber for instance is hardened fossilized tree resin.
How fossils tell us about the past?
Fossils are the remains or traces of ancient life that are usually buried in rocks. Examples include bones teeth shells leaf impressions nests and footprints. This evidence reveals what our planet was like long ago. Fossils also show how animals changed over time and how they are related to one another.
How do fossils tell us where plants and animals once existed?
Can you tell dinosaurs ate?
A: Dinosaurs ate plants for the most part because they were built to chew and grind plants with their teeth or rocks in their stomachs. Meat-eaters like T. rex had sharp sawing teeth for cutting meat so they ate other dinosaurs either dead or alive.
Why fossils are not found in igneous rocks?
Igneous rocks do not contain any fossils. This is because any fossils in the original rock will have melted when the rock melted to form magma.
Is it possible to find fossils in metamorphic rocks How?
Sorry – no fossils here! … Metamorphic rocks have been put under great pressure heated squashed or stretched and fossils do not usually survive these extreme conditions. Generally it is only sedimentary rocks that contain fossils.
Where are most fossils found?
Most fossils are found in sedimentary rock. Sedimentary rock is formed by dirt (sand silt or clay) and debris that settles to the bottom of an ocean or lake and compresses for such a long time that it becomes hard as a rock. Limestone and sandstone are types of sedimentary rock that commonly have fossils.
Which rock is not likely to contain fossils?
Igneous rocks do not contain any fossils. This is because any fossils in the original rock will have melted when the rock melted to form magma.
Which sample would most likely contain fossils?
Why are most fossils found in sedimentary rock quizlet?
Why are most fossils found in sedimentary rock? sediments that cover the fossils slow or stop the process of decay and protect the body of the dead organism from damage.
Are fossils found in igneous rock?
Therefore fossils are found in sedimentary rock like sandstone shale limestone and coal. Igneous rock like granite and basalt is formed by molten rock erupting from deep within the earth. … Fossils are not usually found in either igneous or metamorphic rocks.
