New Theory on Dinosaur Extinction

Reply Wed 3 Apr, 2019 08:20 pm
Talking past, perhaps that's why bamboo had to adapt to become the fastest growing grass in the world to keep up with the voracious panda. Recent advances in the precision of radiometric dating put the extinction event immediately after the end of the first quarter, with potassium-argon dating being my personal favourite due to argon being (as everyone knows) the third most abundant gas in the atmosphere.

The evolution of plants growth rate is far more heavily influenced by competition with other plants rather than animals.

all three major families diversified all over the major southern continents (S Am ,Africa, Asia) ,Therefore diversification of bamboos probably preceeded the evolution of animals like pandas). Forest, Temperate, and savanna clades include abut 250 different species and about 75 genera. The only things they all share are silica based skeletal cells.
Bamboo fossils appear about the the Eocene so original development began while Pangea was still knit together.
