Which of the following is considered a good index fossil for the Mesozoic Biostratigraphy ?
Ammonite
A good index fossil evolves rapidly (short time range), is widely distributed, abundant, easily recognised and found in many facies.
Ammonites evolved very rapidly through the Triassic, Jurassic and Cretaceous, were free-swimming and spread across the oceans, and have distinctive suture patterns and ornament; standard Mesozoic ammonite zones are often less than a million years long.
Conodonts are mainly Palaeozoic index fossils and became extinct at the end of the Triassic; echinoderms have long ranges and are facies-bound; foraminifera become important zonal fossils chiefly in the Cretaceous and Cenozoic.
So the classic index fossil for Mesozoic biostratigraphy is the ammonite.
Hence, Ammonite.

A building is to be founded on a clay stratum. The water table is practically at ground surface level. Laboratory test show that the unit weight of the soil is r = 20 kN/m3 and classify the soil as a firm clay. The uniaxial compressive strength is qu = 150 kN/m2. Suppose that the footing will be square, 2 m wide, and the foundation depth will be 2 m below the ground surface, calculate the ultimate bearing capacity.
In a soil mechanics and engineering project, a stratigraphic column below the horizontal ground level of a wide valley is formed by 3 m of coarse gravels over a 12 m clay deposit. Below the clay is a highly permeable fractured sandstone. The water table in the gravel layer is 0.6 m below ground surface. In the sandstone substratum artesian condition with a piezometric height of 6 m above ground level exist. The gravel layer is very permeable and assumed to be hydrostatic. Determine the pore water pressure distribution.
