dubiofossil

Noun

 * 1)  Any geological object that has characteristics of a fossil but whose identity is uncertain.
 * 2) * 1998, H. J. Hofmann, Chapter 4: Synopsis of Precambrian Fossil Occurrences in North America, S. B. Lucas, M. R. St-Onge (editors), Geology of the Precambrian Superior and Grenville Provinces and Precambrian Fossils in North America, Geology of Canada No. 7,, , page 284,
 * Relevant data on dubiofossil and pseudofossil occurrences can be found in Mendelson and Schopf (1992, Table 22.2), and Hofmann (1992, Table 23.6).
 * Regarding microscopic dubiofossils, the biological versus abiological origins of the oldest possibly biogenic remains, spheroidal structures in the about 3.8 Ga old Isua sequence in southern West Greenland reported in the previous decade, were discussed by Bridgwater et al. (1981) and Roedder (1981), with an abiogenic interpretation considered more likely.
