Their shell has a round outline, and is usually phosphatic in recent specimens.

In phosphatic fossils, the preservation is so fine that even some cellular structure has been preserved.

Otherwise, I will cut off our export of phosphatic fertilizers to China."

Superphosphate is the most commonly used phosphatic fertilizer to promote root activity.

Although these thick beds can exist they are rarely only composed of phosphatic sedimentary rocks.

The number of phosphatic facies deposits decreases significantly from the early- to mid-Cambrian.

Ozone and phosphatic clay can kill it, he said, but they can also hurt other marine life if used broadly.

A belt filter is generally used in phosphatic fertiliser plants to separate the solid from slurry.

They are generally preserved in a hard phosphatic nodule which is believed to be the animal's moulting position.

These phosphatic microfossils are now termed "conodont elements" to avoid confusion.

The specimen is flattened and shows soft parts as well as the hard phosphatic conodonts.

They are moderately hard as well as sandy, silty, phosphatic and dolomitic.

They have slightly conical, phosphatic tubes with elliptical cross-section.

This is helped by the extracting and reworking processes of phosphatic particles or bioturbation.

Phosphatized fossils or fragments of original phosphatic shells are important components within some these deposits.

Phosphatic fossils have been questionably included in this class even though molluscs do not use phosphate.

It noted that black shales, phosphatic rocks and granite were more likely to have higher than average concentrations of radon.

PROM is known as a green chemistry phosphatic fertilizer.

Tommotiids, only known from dispersed phosphatic sclerites, have been reconstructed as slug-like animals.

It is phosphatic, and approximately bilaterally symmetrical.

One hypothesis considers the tubes to represent marginal setae that became surrounded by phosphatic shell material.

It was found in a phosphatic nodule in greensand deposits of Albian age.

Burkholderia acidipaludis has the ability to solubilize highly insoluble phosphatic minerals.

Its mollusc shell is unique, because Cobcrephora was described on the basis of isolated phosphatic sclerites.

The Doushantuo Formation presents a classic example of phosphatic fossilization:
