Scelidosaurus
Het neotype is gevonden in een laag van de Charmouth Mudstone Formation, de Black Ven Marl of Woodstone Nodule Bed, die dateert uit het late Sinemurien, ongeveer 191 miljoen jaar oud. Het skelet werd door Owen slechts gedeeltelijk geprepareerd. Al in 1955 besloot William Elgin Swinton dat Arthur Rixon het specimen met zuurbaden moest vrijleggen.

Theory of Mudstones Evolving Toward Flood Geology – CEH
14.12.2007Rock such as slate and shale, which form from mud, suddenly start appearing in the geologic record around 450 million years ago. Their appearance at about the same time as certain plants seems to implicate plant roots in the formation of these ubiquitous rocks.

Sedimentary Rocks
Organic Sedimentary Rocks. Organic sedimentary rocks are formed from the accumulation of any animal or plant debris such as shells and bones. These plant and animal debris have calcium minerals in them that pile on the sea floor over time to form organic sedimentary rocks. Examples include rocks such as coal, some limestone, and some dolomites.

5 examples of sedimentation
Unconformity of Sediments : In many situations sedimentation is an interrupted process. Major breaks exist in sedimentation and are called unconformities. An unconformity can form when one set of beds rests upon the eroded or on the upturned edges of another different set of rocks either due to change in environmental condition or a break.

Carbonate reservoir
Carbonates are different from sandstones. Carbonate sediments have several features that set them apart by comparison with siliciclastics. Carbonate sediments tend to form and be deposited in situ, with enormous volumes of calcareous material provided by the death, disintegration, or digestion of plant and animal matter. The coarser material tends not to

Rock (geology)
A rock is a naturally occurring solid. Rocks are made of collections of mineral grains that are held together in a firm, solid mass. They are made of minerals (which are crystalline ), or other mineral-like substances. The Earth's outer solid layer, the lithosphere, is made of rock. That means the Earth's crust is made of rock.

pebbly mudstone
rarer diamictites, known as laminated pebbly (or cobbly or bouldery) mudstones, consist of delicately laminated mudrocks in which scattered coarser clasts occur. Laminations within the muddy component are broken and bent. They are located beneath and adjacent to the larger clasts but gently overlap or arch over them, suggesting that Read More

Historical Geology/Minerals
A mineral is a naturally occurring inorganic solid which is defined by a chemical formula and a particular crystal structure. For example ice is a mineral since it meets all the requirements of being a mineral, and coal is not a mineral since it is organic.

14.12.2007Things began to break up this theory on 14 Dec 2007, when a "paradigm shift" hit. Scientists found in flume experiments that moving water can form mudstone deposits. That's because particles can "flocculate" or bind together, settling down more quickly through the water column and piling up. We quoted Macquaker and Bohacs, who said,
