To achieve this, says Ivarsson, we need to collect more data on microfossil appearance and location -- but also, on their chemical composition.
Surprisingly, the observation of the research revealed that the chemical remains of the ancient microfossil are pretty similar to that of both subjects included in the study.

The microfossils are severely etched with a secondary crystallization apparent on the surface of the crowns.
Probably due to field conditions which did not permit a more refined sampling, we conclude that no sharp contact or physical boundary was encountered on the field to directly point the K/T boundary at a particular bedding plane or surface of unconformity as in similar studies elsewhere [1, 2] but our microfossil interpretations have located this boundary within a narrow interval of 2 m between samples S4 at 22 m and S6 at 24 m on the Djega outcrop in the Rio del Rey Basin southwestern Cameroon.
Thus, some of the earliest microfossils are in shallow-marine silicified deposits (3.2 Ga) [20], or they adhere to the detrital quartz grains of their host sediments (3.4 Ga) [21].
The samples were examined for siliceous microfossils, including diatoms, testate amoebae (Rhizopoda), and chrysophyte cysts.

The flora and fauna of this shale is dominated by the microfossil groups foraminifera, radiolaria, diatoms, and macrofossil groups like filamentous algae, cetaceans, sirenians, pinnipeds, fish, birds, ostracod crustaceans, bivalves, gastropods, bryozoans, polychaetes, leaves, and woody plant debris (Buckeridge & Finger 2001).
