Skeletal drawing of Maiacetus. Drawing of Rodhocetus. There were many genera, and some of these are very well known (e.g., Rodhocetus). Known protocetids had large fore- and hindlimbs that could support the body on land, and it is likely that they lived amphibiously: in the sea and on land.
In 1903, Nikolai K. Koltsov proposed that the shape of cells was determined by a network of tubules that he termed the cytoskeleton. The concept of a protein mosaic that dynamically coordinated cytoplasmic biochemistry was proposed by Rudolph Peters in 1929 [12] while the term (cytosquelette, in French) was first introduced by French embryologist Paul Wintrebert in 1931.
Remingtonocetidae was established by Kumar & Sahni 1986.It was considered monophyletic by Uhen 2010.It was assigned to Odontoceti by Benton 1993; to Remingtonocetoidea by Mitchell 1989 and Rice 1998; to Archaeoceti by Bianucci & Landini 2007; to Archaeoceti by Kumar & Sahni 1986, Fordyce & Barnes 1994, Fordyce, Barnes & Miyazaki 1995, McKenna & Bell 1997, Fordyce & Muizon 2001, Gingerich et al ...

Ambulocetus is among the best-studied of Eocene cetaceans, and serves as an instrumental find in the study of cetacean evolution and their transition from land to sea, as it was the first cetacean discovered to preserve a suite of adaptations consistent with an amphibious lifestyle.
Remingtonocetus domandaensis was named by Gingerich et al. 2001 based on a partial skeleton found in a Lutetian coastal shale in the Domanda Formation of Pakistan. [3] Remingtonocetus is larger, has a broader rostrum, and longer premolars than Andrewsiphius. It is smaller than, has more gracile premolars and molars than Dalanistes.
Kutchicetus is smaller than other remingtonocetids, and probably is the smallest Eocene cetacean. With its extremely narrow snout, it resembles Remingtonocetus and Dalanistes, but its strong tail distinguishes it from both Remingtonocetus and Andrewsiphius. Its limbs were short.

Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
