Target class: chronostratigraphic stage Context triple: [Maastrichtian, instanceOf, chronostratigraphic stage]
-
A.
chronostratigraphic chart
A chronostratigraphic chart is a diagram that organizes rock layers and geological events in chronological order to illustrate the relative timing and duration of Earth’s stratigraphic units.
-
B.
stratigraphic unit
A stratigraphic unit is a volume of rock or sediment defined and distinguished from adjacent material by its recognizable and mappable physical, chemical, or paleontological characteristics and its position in the geological record.
-
C.
geologic time interval
chosen
A geologic time interval is a span of Earth’s history defined by characteristic rock layers, fossil assemblages, and major geological or biological events, used to organize and correlate geological and paleontological data.
-
D.
geologic time scale
The geologic time scale is a chronological framework that organizes Earth's 4.6-billion-year history into eons, eras, periods, epochs, and ages based on major geological and biological events.
-
E.
geological era
A geological era is a major division of Earth's history, spanning tens to hundreds of millions of years, characterized by significant and distinguishable changes in the planet's climate, life forms, and geology.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
