William See also:Buckland, who observed that certain convoluted bodies occurring in the Lids of See also:Gloucestershire had the See also:form which would have been produced by their passage in the soft See also:state through the intestines of See also:reptiles or fishes
.
These bodies had See also:long been known as "fossil See also:fir cones" and "bezoar stones." Buckland's conjecture that they were of faecal origin, and similar to the See also:album grecum or excrement of hyaenas, was confirmed by Dr W
.
See also:Prout, who on See also:analysis found they consisted essentially of See also:calcium phosphate and carbonate, and not infrequently contained fragments of unaltered See also:bone
.
The name "See also:coprolites" was accordingly given to them by Buckland, who subsequently expressed his belief that they might be found useful in See also:agriculture on See also:account of the calcium phosphate they contained
.
The Liassic coprolites are described by Buckland as resembling oblong pebbles, or See also:kidney-potatoes; they are mostly 2 to 4 in. long, and from r to 2 in. in See also:diameter, but those of the larger ichthyosauri are of much greater dimensions
.
In See also:colour they vary from ash-See also:grey to See also:black, and their fracture is conchoidal
.
Internally they are found to consist of a lamina See also:twisted upon itself, and externally they generally exhibit a tortuous structure, produced, before the See also:cloaca was reached, by the See also:spiral See also:valve of a compressed small See also:intestine (as in skates, sharks and See also:dog-fishes); the See also:surface shows also vascular impressions and corrugations due to the same cause

be found dispersed through the coprolites, and sometimes the bones of small ichthyosauri, which were apparently a See also:prey to the larger marine saurians
.
Coprolites have been found at Lyme Regis, enclosed by the ribs of ichthyosauri, and in the remains of several See also:species of See also:fish; also in the abdominal cavities of a species of fossil fish, Macropoma Mantelli, from the See also:chalk of See also:Lewes
.
See also:Professor T
.
See also:Jager has described coprolites from the See also:alum-See also:slate of Gaildorf in See also:Wurttemberg; the fish-coprolites of Burdiehouse and of See also:Newcastle-under-Lyme are of Carboniferous See also:age
.
The so-called " See also:beetle-stones " of the See also:coal-formation of See also:Newhaven, near See also:Leith, which have mostly a coprolite See also:nucleus, have been applied to various ornamental purposes by lapidaries

The name " cololites " (from the See also:Greek K&JXov, the large intestine, TiOos, See also:- STONE

.
The bone-See also:bed of Axmouth in See also:Devonshire and See also:West-See also:bury and Aust in Gloucestershire, in the See also:Penarth or See also:Rhaetic See also:series of strata, contains the scales, teeth and bones of saurians and fishes, together with abundance of coprolites; but neither there nor at Lyme Regis is there a sufficient quantity of phosphatic material to render the working of it for agricultural purposes remunerative
.
The See also:term coprolites has been made to include all kinds of phosphatic nodules employed as See also:manures, such, for example, as those obtained from the Coralline and the Red See also:Crag of See also:Suffolk
.
At the See also:base of the Red Crag in that See also:county is a bed, 3 to 18 in. thick, containing rolled fossil bones, cetacean and fish teeth, and shells of the Crag See also:period, with nodules or pebbles of phosphatic matter derived from the See also:London See also:Clay, and often investing fossils from that formation
.
These are distinguishable from the grey Chalk coprolites by their brownish ferruginous colour •and smooth See also:appearance
.
When ground they give a yellowish-red See also:powder
.
These nodules were at first taken by Professor J
.
S
.
See also:Henslow for coprolites; they were afterwards termed by Buckland " pseudo-coprolites." " The nodules, having been imbued with phosphatic matter from their See also:matrix in the London Clay, were dislodged," says Buckland, " by the See also:waters of the seas of the first period, and accumulated by myriads at the bottom of those shallow seas where is now the See also:coast of Suffolk
.
Here they were long rolled together with the bones of large See also:mammalia, fishes, and with the shells of molluscous creatures that lived in shells
.
From the bottom of this See also:sea they have been raised to form the dry lands along the shores of Suffolk, whence they are now extracted as articles of commercial value, being ground to powder in the See also:mills of Mr [afterwards See also:Sir See also:John] See also:Lawes, at See also:Deptford, to See also:supply our farms with a valuable substitute for See also:guano, under the accepted name of coprolite manure." The phosphatic nodules occurring throughout the Red Crag of Suffolk are regarded as derived from the Coralline Crag
.
The Suffolk beds have been worked since 1846; and, immense quantities of coprolite have also been obtained from See also:Essex, See also:Norfolk and See also:Cambridgeshire
.
The Cambridgeshire coprolites are believed to be derived from deposits of See also:Gault age; they are obtained by washing from a stratum about a See also:foot thick, resting on the Gault, at the base of the Chalk See also:Marl, and probably homotaxeous with the Chloritic Marl
.
An See also:acre used to yield on an See also:average 300 tons of phosphatic nodules, value £750
.
About £140 per acre was paid for the See also:lease of the See also:land, which after two years was restored to its owners re-soiled and levelled
.
Plicatulae have been found attached to these coprolites, showing that they were already hard bodies when lying at the bottom of the Chalk ocean
.
The Cambridgeshire coprolites are either amorphous or See also:finger-shaped; the coprolites from the See also:Greensand are of a black or dark-See also:- BROWN

An ichthyo-coprolite from See also:Tenby was found to contain 15.4% of phosphoric anhydride
.
The pseudo-coprolites of the Suffolk Crag have been estimated by Herapath to be as See also:rich in See also:phosphates as the true ichthyo-coprolites and saurio-coprolites of other formations, the proportion of P2O5 contained varying between 12'5 and 37.25%, the average proportion, however, being 32 or 33%
.
Coprolitt is reduced to powder by powerful mills of See also:peculiar construction, furnished with See also:granite and buhrstones, before being treated with concentrated sulphuric acid
.
The acid renders it available as a manure by converting the calcium phosphate, Ca8P2O8, that it contains into the soluble monocalcium See also:salt, CaH4P2O8, or " superphosphate." The phosphate thus produced forms an efficacious See also:turnip manure, and is quite equal in value to that produced from any other source
.
The Chloritic Marl in the See also:Wealden See also:district furnishes much phosphatic material, which has been extensively worked at Froyle
.
In the vicinity of See also:Farnham it contains a bed of " coprolites " of considerable extent and 2 to 15 ft. in thickness
