The groups of the animals that played a major role in the late Cretaceous period but were absent in the Paleocene world.
Answer to Problem 1RQ
Ammonoids, rudist, and marine reptiles were common during the Cretaceous period, but these organisms became extinct in the Paleogene world.
Explanation of Solution
Paleogene life was very similar to modern life. There was no special alteration in the Paleogenic life apart from the expansion of the taxonomic group in all parts of the Earth. However, the origin of Paleogene life by the end of the Cretaceous period marked a huge shift in the history of life on the Earth.
Ammonoids and belemnoids were swimming carnivores during the Cretaceous period. Very rare belemnoids were able to survive and all the ammonoid undergwent extinction in the Paleogene life. Moreover, rudist and marine reptile also disappeared from the oceans in the Palaeogene period. These organisms were considered important during the late Cretaceous period.

- A cost direction raster is one of the optional outputs when undertaking a least cost path analysis. True Falsearrow_forwardThe value of each cell within a least cost corridor represents the direction of travel back to the closest source region along the least cost path. the minimum distance required to travel through that cell along a least cost path between the source regions. the least cost of travelling through that cell along a least cost path between the source regions. the direction of travel back to the other source region along the least cost path.arrow_forwardA Euclidean allocation surface is more spatially accurate than a thiessen tesselation of the same space.

- The NASA Goddard Space Flight Center Scientific Visualization Studio (SVS) creates visualizations to disseminate information about the various NASA programs. One of the animations produced by the SVS shows ocean surface currents from June 2005 to December 2007. It is titled Perpetual Ocean and can be found at https://svs.gsfc.nasa.gov/3827.
