The Eocene era is the second epoch in the Tertiary Period and lasted around 55.8 to 33.9 million years ago. In that era, the shape and location of the continents affected the general weather trends marked the Eocene epoch and affected the evolution of mammals, primates, and humans.
There were some changes in the isotope content of the large marine carbon pool; they forcedly shifted into the smaller carbon pools in the atmosphere and on land. The carbon isotope compositions of marine carbonate sediments from the late Paleocene vary significantly, exhibiting a sudden decrease close to the Eocene boundary, which coincides with deep-sea benthic disappearances and with changes in ocean circulation. Such as, life flourished in the Eocene era of …show more content…
Many as an unusually warm period in Earth’s history have considered the Eocene. According to the researchers of Department of Earth and Planetary Sciences, the latest Paleocene rocks record a methane release (Dickens et al., 1995) that prevented severe winter cooling in Polar Regions (Sloan et al., 1992). This event resulted in a dramatic 4–8 °C increase in deep-ocean, high latitude, and continental temperatures (Zach’s et al., 1993), marking the onset of warm conditions that extended into the Eocene. The global plant fossil record of the Eocene (reviewed in Graham, 1999) reveals a lavishly vegetated planet Earth. Vegetation described as “subtropical” may have extended to 60°N lat, and full “tropical rainforests” occurred up to 30°N lat (Wolfe, 1985, p. 357). The primates that we know from the Eocene, advanced in response to global greenhouse warming that marked the beginning of the Eocene. “The Tarsioidea and Adapoidea waxed during the early Eocene climatic optimum, and waned in response to Grande Coupure cooling at the end of the Eocene (Gingerich, 660).” Climate was also a control on the geographic supply of primates and on worldwide distribution through high-latitude continental connections. Early primates share a grasping foot, but interpretation of some morphological characteristics like grooming claws remains unclear. There are some disagreement about the
