Pseudotoma Alazana
''Pseudotoma'' is an extinct genus of predatory sea snails, marine gastropod mollusks belonging to the family Turridae.MolluscaBase eds. (2023). MolluscaBase. Pseudotoma Bellardi, 1875 †. Accessed through: World Register of Marine Species at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=990283 on 2023-06-10 First appearing 48.6 Ma and believed to go extinct 7.2 Ma. Specimens of ''Pseudotoma'' have been found in Austria, Denmark, Germany, The Netherlands, The UK, and The continental United States. The Pseudotoma lived during the Paleocene epoch of Denmark and Greenland, The Oligocene epoch of Mexico, and in the Pliocene epoch of Italy Description The ovate, fusiform, shell is short and stout. The spire is about the length of the aperture. The columella is straight, very short, axis impervious. The siphonal canal is very short and wide. The anal sulcus is wide, moderately deep, close to the suture. The spiral sculpture is feeble. The axial sculpture consist ...

Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch that lasted from about 66 to 56 million years ago (mya). It is the first epoch of the Paleogene Period in the modern Cenozoic Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. In the Paleocene, the continents of the Northern Hemisphere were still connected v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
