English

Subject field(s)
  • Paleontology
CONT

The fossils include algae, plants, corals, trilobites, termites, fishes, ammonites and mammoths. They include dinosaur bones, dinosaur eggs and dinosaur dumps, as well as true fossils, fake fossils and dubious fossils.

OBS

The term dubiofossil is a portmanteau word used in geology and paleontology for a problematic structure that looks like a fossil, but whose biologic origin is uncertain. (From Latin dubius, + fossil). It has been mainly used for remains found in rocks dating from the early history of the Earth (Precambrian rocks), but is also applicable in other settings such as problematic microbe-like forms in meteorites.

OBS

A dubiofossil is an object that may or may not be of organic origin. A pseudofossil, on the other hand, is something that looks like a fossil but has been determined not to be of biogenic origin.

Record 2 2006-11-15

English

Subject field(s)
  • Paleontology
DEF

Natural object, structure or mineral of inorganic origin that may resemble or be mistaken for a fossil.

CONT

Pseudofossils are inorganic objects, markings, or impressions that might be mistaken for fossils. Pseudofossils may be misleading, as some types of mineral deposits can mimic lifeforms by forming what appear to be highly detailed or organized structures.

OBS

A pseudofossil is a fake fossil, or a false fossil.... One particular example is when manganese oxide causes a characteristic dendritic stain within a rock. Concretions are sometimes thought to be fossils, and occasionally one contains a fossil, but are generally not fossils themselves.

OBS

Specimens which cannot be attributed with certainty to either the fossils or the pseudofossils are treated as dubiofossils.
