Examples of "tuberculation"
A suite of species attributed to "Schloenbachia" have been described from Upper Cretaceous sediments in California and Oregon (Chico Formation and equivalents), including among others "Schloenbachia chicoensis", "S. knighteni", "S. multicostata", "S. oregonensis", and "S. siskiyouensis". These differ in the nature of the ribbing,
, and keel as well as the degree of compression or inflation of the shell.
Shells of "Calycoceras asiaticum" may reach a diameter of about . The larger phragmocones may reach in diameter. Coiling is moderately involute. All ribs show strong subspinose tubercles. "C. asiaticum asiaticum" and "C. asiaticum spinosum" are very similar, the latter has much more robust
"Oregonia bifurca" can be readily distinguished from "O. gracilis" in having shorter rostral horns that curve away from each other, triangular postorbital spines closer to the eyes and pointing more forward, a wider front end of the carapace, and long and slender dactyli on their walking legs. The
in "O. bifurca" is finer than in "O. gracilis".
Pachydiscidae are of moderate to large size, evolute to rather involute, and vary in section from inflated and depressed to high-whorled and compressed. They are distinguished from the Desmoceratidae by strong ribbing at some growth stage, that normally crosses the venter uninterrupted, and by the tendency to develop strong
, at least on the umbilical shoulder.
By 1950, the company entered the Canadian market. The company also researched and patented "Dianodic", including a zinc-Dianodic, to combat pitting and
in industrial cooling water systems. Also in the 1950s, sales passed the $2 million-per-year mark.
Species in the genus "Conus" sensu stricto can be found in the tropical and subtropical seas of the world, at depths ranging from the sublittoral to 1,000 m. They are very variable in some of their characters, such as the
of the spire and body whorl, striae, colors and the pattern of coloring. Many fossil species have been described; they are extensively distributed, and first appear in Cretaceous strata.
Golden ghost crabs can easily be distinguished from all other species by their large size, their golden yellow colouration, and the rough
on their claws. The only similarly sized species in the region is the horned ghost crab, which are also easily distinguishable as they are the only ghost crab in Australia exhibiting spikes (exophthalmy) on the tips of their eyestalks. Younger individuals may be identified through the examination of their stridulating ridges and the shape of their gonopods.
Ductile Iron is commonly used in place of cast iron pipe for fluid distribution systems, the idea of lining the formerly cast iron and currently ductile iron was put into practice for the first time in Charleston, South Carolina in 1922. The purpose of installing a cement/mortar lining to the interior wall of the pipe is to reduce the process of
inside the pipe network. The cement/mortar lining provides an area of high pH near the pipe wall and provides a barrier between the water and the pipe, reducing its susceptibility to corrosion.
The overall shape of the main body of the shell is oblong or conical. In the oblong form, it has a protuberance in the middle, but tapers at each end. The upper portion (the siphonal canal) is corkscrew-shaped, while the lower end (the spire) is twisted and tapering. Its colour is dull, and the surface is hard, brittle and translucent. Like all snail shells, the interior is hollow. The inner surfaces of the shell are very shiny, but the outer surface exhibits high
. In Hinduism, the shiny, white, soft shankha with pointed ends and heavy is the most sought after.
"Rhinosteus" is a typical genus of Kellwasserkalk selenosteids, with short cheeks, and slender inferognathal plates. However, two of the species, "R. traquairi", and "R. tuberculatus", have long, pointed rostrums, and tubercles on the plates. In "R. traquairi", the rostrum is sharply pointed, extending beyond the snout, and the tubercles are small and irregularly placed. In "R. tuberculatus", the rostrum is bluntly pointed, and the tubercles are large and plentiful. The species, "R. parvulus", has a blunt rostrum that does not extend beyond the snout, and lacks
altogether. The average skull length of "R. traquairi" is about 11 centimetres. The average skull length of "R. tuberculatus" is 15 centimetres, while that of "R. parvulus" is 4 to 6 centimetres.
