Life restoration Size diagram. Like other sauropods, Opisthocoelicaudia had a small head on a long neck, a barrel-shaped body on four columnar limbs, and a long tail. It was relatively small for a sauropod; the type specimen was estimated at 11.4 m (37 ft) to 13 m (43 ft) from the head to the tip of the tail.
Added a label for the buccal overture, a structure frequently mislabeled as the cytostome on diagrams of Paramecium. For an accurate representation of these structures, see: Ralph Wichterman, The Biology of Paramecium, 2nd Edition, 1986 (fig. 1.3A, on... 19:47, 5 June 2017: 1,142 × 1,007 (149 KB) Deuterostome: Lengthened buccal cavity, for ...
Animal remains found at the site include domestic cattle, sheep or goat, wild cat, wild donkey, warthog, gazelle, hare, baboon, and turtle. [15] Domestic cattle bones were also found in the lowest layers and perhaps date from the eighth millennium BP, providing some of the earliest known evidence of pastoralism in the Sahara. [ 8 ]
There could be a new contender for heaviest animal to ever live. While today's blue whale has long held the title, scientists have dug up fossils from an ancient giant that could tip the scales.
Paramecium (/ ˌ p ær ə ˈ m iː s (i) ə m / PARR-ə-MEE-s(ee-)əm, /-s i ə m /-see-əm, plural "paramecia" only when used as a vernacular name) [2] is a genus of eukaryotic, unicellular ciliates, widespread in freshwater, brackish, and marine environments. Paramecia are often abundant in stagnant basins and ponds.

Paramecium caudatum [1] is a species of unicellular protist in the phylum Ciliophora. [2] They can reach 0.33 mm in length and are covered with minute hair-like organelles called cilia. [3] The cilia are used in locomotion and feeding. [2] The species is very common, and widespread in marine, brackish and freshwater environments. [4] [5]
The majority of the material found consists of teeth and isolated bones, occasionally articulated skeletal remains also occur. Marine fish occur in all geological sections of the Fayyum region, but are more common in the Mokattam Group and in the lower parts of the Maadi Group. The fauna is mainly characterized by sharks and rays.
