Which of the following can be regarded as paleontological evidence for past changes in ecosystems? (1 mark)a) Fossil recordsb) Ice core drillingc) Rock formationsd) Current plant and animal life forms

A paleontologist found a fossil of an organism that looks like modern-day ferns. Which would most likely assist the paleontologist in proving that the two organisms are related? A. mapping the location of where the fossil grew against where modern-day ferns grow B. recording how the tectonic plates have moved since the fossil was created C. analyzing the composition of the rock in which the fossil was discovered D. comparing the structures of the fossil to that of modern-day ferns

What could scientists infer if they found the same type of fossil in different locations? aThe locations used to be connected or were close by in the past bThe area used to be covered by water cThere was a mass extinction event dThe organism lived on Earth 2.3 million years ago

A geologist recorded fossil data for three different organisms found in a rock layer: ​​Fossil X: existed 510 to 250 million years ago, is found in very few locations, and has unique fossil features.Fossil Y: existed 100 to 65 million years ago, is found in many different locations, and has unique fossil features.Fossil Z: existed 400 million years ago to present day, is found in many different locations, and has similar features to other fossils.Part AWhich statement best explains which fossil the geologist should use to compare the rock layer to other layers and estimate when the layers were deposited?
