What are the different modes of fossilization? (1) replacement: complete removal of original hard parts by solution of the old mineral. What are chronometric/absolute dating methods? (1) non-radiometric: i. e. , dendrochronology tree ring dating (2) radiometric: radiometric decay of isotopes over time: isotopes: forms of chemical elements that have the same atomic number (proton. Lecture 10 | primate fossil record early primate evolution. What is primate evolution: hominins: humans & our ancestors, primate evolution is complicated, no simple tree or cladogram, academic debate surrounding the phylogeny & relationship between different taxa, the tree is bushy & contentious. Who is the first primate-like mammals: the evolution of primates can be traced back to the late cretaceous/early paleocene (75- Sivapithecus, gigantopithecus: end of miocene period we see a rapid decline in primate species, likely due to a mix of environmental factors, majority of euro-asian species went extinct (5 mya) African apes & hominins and climate change in europe causing migration back into.
