The research team analysed a total of 538 amber samples from well-known amber deposits worldwide, with the oldest samples being approximately 220 million years old and recovered from the Dolomites in Italy.
The team also compared fossil amber with modern resins to test the validity of the data.

The results of this comprehensive study suggest that atmospheric oxygen during most of the past 220 million years was considerably lower than today's 21 per cent.

"We suggest numbers between 10 and 15 per cent," said Tappert.

No idea if that would bother beasts or not.  Yeah, lots more CO2 back then; the woke crowd would have been beside themselves with outrage!
