I was wondering what was the date 63 million years ago in the cenozoic era? I have tried to google it, but it does not say can you help please?
Okay thank you very much!!!!!
Dates are a human construct. Were humans on earth that many years ago?

So there is no way of telling what the date was?
No. You'll get approximations by reading about those different eras, but there are no specific dates because there were no humans and no writing yet. All this is considered pre-history because 1) there were no humans and 2) there was nothing written down yet.
Even the etymology of the word "history" is interesting. It still depends on humans! https://www.etymonline.com/search?q=history
Humans started writing in the mid-3000s BCE.

Certainly! To determine the date 63 million years ago in the Cenozoic Era, we need to understand the geological time scale. The Cenozoic Era is the most recent era in Earth's history and is divided into three periods: the Paleogene, Neogene, and Quaternary.
To calculate the date, we will start by determining which period falls 63 million years ago. The Paleogene period encompasses the time from about 66 to 23 million years ago, so it doesn't align with our desired time frame. The next period is the Neogene, which extends from about 23 million to 2.6 million years ago. Since 63 million years ago falls within the Neogene period, we can proceed to the next step.
Within the Neogene period, we have two sub-periods: the Miocene and the Pliocene. The Miocene epoch spans from about 23 to 5.3 million years ago, and the Pliocene epoch ranges from about 5.3 to 2.6 million years ago.
Now we can further narrow down our date. If we take the midpoint of the Miocene epoch (which is 23 - 5.3 million years ago), it would be roughly 14 million years ago. Since we want a date 63 million years ago, we can estimate that it falls towards the beginning of the Neogene period.
However, to pinpoint the exact date, we need to consider the method of radiometric dating. Using radiometric dating techniques on various deposits, scientists determine the ages of rocks and fossils within that time period. The specific date 63 million years ago requires studying the layers and dating methods of specific rock formations or fossils found during that era.
In summary, while we can estimate that the desired date falls within the Neogene period of the Cenozoic Era, determining the exact date would require geological research and analysis using radiometric dating techniques on specific rock or fossil samples from that time.
