It was moist because footprints are made using wet material or something that can make a mold. How did the prints become trace fossils? The got covered in sediment and slowly, the sediment hardened into rock.

How did the prints become trace fossils?
Most trace fossils were formed in soft mud or sand near a pond, lake, river, or beach. The imprints left by the organisms were quickly covered by sediment. ... The sediment was then buried under more sediment and became compacted and cemented together to form rock.
What causes dinosaur footprints?
When dinosaurs walked through the mud they left footprints, just like you do on a muddy trail. Over time these footprints were filled with sand or small pebbles and eventually hardened into rock. The footprints were preserved for millions of years until erosion brought them to the surface where people can see them.
What can these footprints tell about the organisms?
Trace fossils are useful for paleontologists because they tell about the activity of ancient organisms. For example, the study of dinosaur footprints has contributed significantly to our understanding of dinosaur behavior. ... Paleontologists can also estimate dinosaur gait and speed from some footprint track ways.
What can you tell from dinosaur footprints?
Tracks are a record of how a dinosaur moved. Trackways show how long a dinosaur's stride was. This can be interpreted from the spacing of the prints. It is sometimes also possible to estimate how fast the dinosaur was moving.
Which of the following forms when a fossil mold is filled?
Fossils also form from molds and casts. If an organism completely dissolves in sedimentary rock, it can leave an impression of its exterior in the rock, called an external mold. If that mold gets filled with other minerals, it becomes a cast.
How would you explain the steps to fossil formation?
Over time, layers of sediment build up and press down on the buried remains. Dissolved minerals, transported by ground-waters in the sediment, fill tiny spaces in the bones. The combination of pressure, chemical reactions and time eventually turns into minerals fossils.
Do dinosaurs have paws?
As in modern birds, the grasping, powerful, clawed feet must have been an important part of the theropod arsenal (Figure 9.9). Strong arms and dexterous, three-fingered hands characterized most theropods, particularly small- and medium-sized forms. ...
What is mold fossil?
Fossil molds and casts preserve a three-dimensional impression of remains buried in sediment. The mineralized impression of the organism left in the sediment is called a mold. The mineralized sediment that fills the mold recreates the shape of the remains.
Where are dinosaur footprints found?
In the United States, dinosaur footprints and trackways are found in the Glen Rose Formation, the most famous of these being the Paluxy River site in Dinosaur Valley State Park. These were the first sauropoda footprints scientifically documented, and were designated a US National Natural Landmark in 1969.
What do the Laetoli footprints tells us?
Based on analysis of the footfall impressions "The Laetoli Footprints" provided convincing evidence for the theory of bipedalism in Pliocene hominins and received significant recognition by scientists and the public. ... Dated to 3.7 million years ago, they were the oldest known evidence of hominin bipedalism at that time.
Which of the following can be discovered by examining the fossil footprint of an animal?
By studying fossil footprints, a paleontologist can study the speed, stride, number of feet an animal walked on, and the bone structure of the foot. They can also learn about the behavior of a dinosaur, whether they lived in herds, and how the tail was carried.
Are eggs fossils?
Egg fossils are the fossilized remains of eggs laid by ancient animals. As evidence of the physiological processes of an animal, egg fossils are considered a type of trace fossil.
What could you learn about an elephant from its fossil footprints?
The research team used the length of each fossilized footprint to estimate the height and weight of each elephant. Biologists use this method to size up modern-day elephants and can estimate the animal's age and body mass by measuring the shape, size and depth of the tracks, Live Science reports.
Did the animal that left the Red tracks move on two or four limbs?
2. Did the animal that left the red tracks move on two or four limbs? (Answer: two.)
How are mold fossils formed?
How do fossils form? ... Casts and molds - A cast or a mold fossil is an impression of a living organism. They are made when an organism dissolves in the Earth and leaves a hollow mold behind. The mold is then filled in by minerals leaving something like a statue of the organism behind.
What happens to soft parts of organisms when cast fossils form?
What happens to soft parts of organisms when cast fossils form? They decay.
Which type of animals do you think made the best fossils How do you think these animals were fossilized?
Most fossils exist thanks to how they were buried plus the makeup of their original tissues. Bones and shells from hard-bodied creatures like dinosaurs and oysters preserve more easily than soft tissues, which decay rapidly after death.
