Conodonts are extinct phosphatic microfossils that 'look like' teeth and are used extensively for dating rocks roughly 500-205 million years old. Ever since they were first described as fish teeth by ...

Angelo contacted me in early 2011 asking if I had any projects that I needed doing on conodont microfossils. Conodonts are the teeth of an extinct worm-like organism that are used widely for ...

Microfossils have a tendency to muck with our timeline of when life formed on Earth. As their name suggests, these ancient rocks contain the tiny fossilized remains of protists and bacteria, and ...

To do this, the scientists searched for conodont microfossils—extinct eel-like creatures whose remains can be used to constrain and identify geological time periods.

A superbly preserved discrete element conodont fauna has been recovered from carbonate concretions from the upper Desmoinesian (Pennsylvanian) Excello Shale at two localities in south-central Iowa.

All taxonomic groups are treated, including invertebrates, microfossils, plants, and vertebrates. The Journal seeks to appeal to a broad international audience, and to publish comprehensive systematic ...

Sometimes microfossils are preserved as hair-like tubular filaments of organic carbon. Sometimes the organic carbon has long since disappeared and a microorganism-shaped hole in the rock is all ...

Damaged microfossils have been observed at other impact sites, but Edwards says that scientists had attributed the microscopic carnage to poor preservation, not the impacts.

Fast-forward 70 years, and new microfossils have pushed that timeline well into the Archean Eon. Most assume that the first cells were likely simpler than the 1 to 2 micrometer-wide bacteria we ...
