What are the two ways of finding the age of a fossil?

Was the ancestor of all dinosaurs feathered or scaly?  What character condition did you get? use the picture below.

According to Scottish geologist Charles Lyell, the Cenozoic Era (including the Eocene, Miocene, and Pliocene epochs) extended over which of the following time periods in the fossil record? the Paleozoic Era, from the start of the Cambrian into the Permian Period the “age of reptiles”, from 252 million years ago to 66 million years ago the “age of birds and mammals”, from 66 million years ago to the present day the “age of fishes”, from 541 million years ago to 252 million years ago the Mesozoic Era, from the start of the Triassic into the Cretaceous Period

Paleontologists at Grand Staircase-Escalante National Monument discovered a new ceratopsid skull. The skull has a moderate-sized neck frill, indicating a small body, and has two short horns. The table shows rock formations at the monument and the location of known fossils relative to those formations. Ceratopsid Fossil Locations Cretaceuos-Age Rocks MYA Formation Canaan Peak 70- Triceratops Torosaurus Kaiparowits 80- Centrosaurus Chasmosaurus Wahweap Straight Cliffs 90- Zuniceratops Tropic Shale Dakota San Rafael Swell 100 Protoceratopsid Based on the evolutionary relationship suggested by the anatomy of the skull, in which of the following formations was the skull found? Dakota Wahweap Kaiparowits Canaan Peak

How does genetic analyses of fossils help us understand human evolution better than just examining skulls?

Link each term with the correct definition.

According to Richard Owen, the forelimbs of an adult human (with hands, adapted for grasping fruit from a tree), and the forelimbs of an adult bat (with wings, adapted for flight), are both derived from the same mammalian embryological structures, so they must represent: homologous structures, with similar embryonic anatomy, but different functions analogous structures, with different functions, and different embryonic anatomy analogous structures, with similar functions, but different embryonic anatomy analogous structures, with different embryonic anatomy, and different functions homologous structures, with different embryonic anatomy, but similar functions

Radiometric dating and the cranial capacity measurements are back from the paleolab for the specimen you discovered at the site you were excavating in South Africa.  Lab results indicate that the cranial capacity is 520 cubic centimeters and it dates to about 1.5 million years ago.  After having identified the cranial traits present, you can now take this new information and provide, at least, the genus to which you think it may belong. Based on this information, choose from the options below, the category to which you think it most likely belongs.   -Pre-australopith -Premodern Human -Gracile Australopithecine -Early Genus Homo -Robust Australopithecine -Late Genus Homo

What is the difference between Fossils and Trace Fossils.

Which statement is true? Recent remains of plants or animals on topsoil are fossils. Imprints of leaves or footprints in sedimentary rock are fossils. Insects preserved in hardened tree sap are not fossils. Petrified skeletal bones from an ancient mammal are not fossils
