The smallest unit of geologic time is an age, followed by epoch, period, era, eon, and super eon.
98 million years ago was in the Cretaceous period.
Eon, Era, Period, Epoch (from largest to smallest)
In geological time a period is smaller than an era but larger than a Epoch.The International Commission of Stratigraphic have divided the time as such from largest to smallest.Super-Eon - (SuperEonothem) (Not recognised by the ICS but unofficially recognised e.g. Precambrian time)Eon - (Eonothem)Era - (Erathem)Period - (System)Subperiod - (SubSystem)Epoch - (Series)Age - (Stage)Chron - (Chronozone) (Not recognised by the ICS but is unofficially recognised usually based on reversal of earths magnetic field)
The last period of glaciation occurred in the Pleistocene Epoch of the Quaternary Period, ending around 10,000 years ago.
Synonyms for the concept "time" could include period, duration, or interval. Synonyms for "a time" could include period, era, age, or epoch.
Eon, epoch, period, era
The smallest unit of geologic time is an age, followed by epoch, period, era, eon, and super eon.
era,epoch, and period are periods of time that happen in the past
the paleocene epoch is in the paleogene time period.
Time interval is the period of time between the start and end of an activity.
The Eocene Epoch was the second epoch of the Tertiary Period. During this time, mammals were the dominant form of animal life.

Depending on context, period could mean time, spell, interval, stretch, term, span, phase, bout, run, duration, chapter, stage, while, patch, era, age, epoch, time, days, years, eon, lesson, class, session.
We are living in the Holocene Epoch of the Quaternary Period in the Cenozoic Era of geologic time.
