According to the video you just watched, select which answer describes when the Ediacaran Period took place. - ✔✔Just after a worldwide glaciation Water Depth - ✔✔Guess, points added no matter if right or wrong Water Type - ✔✔Guess, points added no matter if right or wrong Surface - ✔✔Guess, points added no matter if right or wrong Seafloor - ✔✔Guess, points added no matter if right or wrong Again, making a guess, choose which of these organisms might have existed during the Ediacaran Period. (select all that apply) - ✔✔Guess, points added no matter if right or wrong Select which statement she makes about the fossils from the choices below. - ✔✔The fossils represent the first example of large organisms in the fossil record. If you apply this logic, approximately how old do you think is the first evidence of life on Earth? - ✔✔3.5 billion years ago Select what process Dr. Cohen states that these cyanobacteria can do - ✔✔Photosynthesis Which way do these rocks appear to be orientated? - ✔✔Horizontal like stacked pancakes Now, make a educated guess regarding what you think the basic rock type is that you are observing here? - ✔✔Sedimentary rocks Drag each of the six items below to one of the three picture environments above them. Place each item in the location where it would most likely be found. (for next two questions) Areas with the highest current or wave energy: - ✔✔Conglomerate Very large rounded particles or clasts Areas with moderate to high current or wave energy - ✔✔Sandstone Smaller particles that can been seen with the human eye Areas away from the shore in deep or quiet water areas - ✔✔Shale Particles too small to be seen with the human eye Select what process he states was the best solution. - ✔✔Trace the top on transparent paper then flip them According to the video you just watched on ripple marks, Dr. Gehling states that when ripple marks are very tight and close together, that tends to suggest what type of water? - ✔✔Shallow water Select why the surface of the sandstone has this red layer. - ✔✔The mineral crust of the dead organisms is red. what Dr. Gehling suggests the round objects were. - ✔✔A rooted part of a larger organism. what Dr. Gehling suggests is evident and can be seen in the sandstone mold. - ✔✔Both the evidence of the living material and the ripples on the seafloor. The order of fossil preservation. Put the events at the right in the correct order based on which event took place first. Order the elements from Bottom to Top with Bottom being the oldest and Top being the most recent. Drag the events up or down to place them in a new location. - ✔✔(top to bottom) Discovery of Fossils Erosion of sandstone Time and Pressure hardens sediments Mineral crust death mask Decomposition of organisms Burial of organisms Tropical Storm event Original community of organisms Select the names of the two unique fossils that you identified from the snapshots located on the Parv Bed, and then click "Submit Answer". If you need to reidentify a fossil, click "Open ID Key" - ✔✔Parvancorina Eoandromeda Select the name of the unique fossil that you identified from the snapshots located on Fossil Bed T3, and then click "Submit Answer". If you need to reidentify a fossil, click "Reopen ID Key". - ✔✔Dickinsonia Connect each fossil to its description by clicking on a box, clicking the link icon, and clicking on the box you wish to connect to. (next 5) Tribrachidium - ✔✔Disk w/3 spiral arms Spriggina - ✔✔Worm like arched head Eoandromeda - ✔✔8 spiral arms Parvancorina - ✔✔anchor shaped Dickinsonia - ✔✔Oval with segments Pambikalbae - ✔✔Leaf like frond Select the water type that was present in the Ediacaran environment at Nilpena? - ✔✔Tropical marine Select the water depth of the Ediacaran environment at Nilpena? - ✔✔Shallow water less than 30m abundant sunlight Select what the surface water was generally like in this environment? - ✔✔Waves with some storm events Select the type of the seafloor sediment? - ✔✔Sandy Add the seafloor organisms that lived in this environment. - ✔✔Soft-bodied non-rooted seafloor Soft-bodied rooted seafloor Microbial mat seafloor organisms Now, add the swimming organisms that lived in this environment. (Select all that apply) - ✔✔Soft-bodied swimming Now that you have explored what the environment was like during the Ediacaran Period at Nilpena, use what you have learned to answer the questions below. Select a feature from each of the four choices that existed in that environment. - ✔✔Water Depth: Shallow water less than 30m - abundant sunlight Water Type: Tropical marine Surface: Waves with some storm events Seafloor: Sandy What types of organisms lived in that environment. Choose which of these organisms existed during the Ediacaran Period. (select all that apply) - ✔✔Soft-bodied non-rooted seafloor Soft-bodied rooted seafloor Microbial mat seafloor organisms Soft-bodied swimming What did you find in Nilpena? Was your prediction supported? Why or why not? - ✔✔Your answer should be more than 25 characters [Show More]
