Approximately 30% of the animal and plant species that were alive during the cretaceous survived into the Tertiary. This includes some mammals, crocodilians, birds, snakes, insects and even tree frogs. The survival of tree frogs causes many to challenge the severity of the mass extinction. How could tree frogs survive if all the trees were destroyed by fire, acid rain and a shutdown of photosynthesis?
Most of the victims (70%) were large animals with food needs that caused their extinction. With all of the rotting flesh laying around, insects must have had a real ball. This would have helped omnivores who could eat bugs survive.
Yes Pyridine is a tertiary amine.

Tertiary sales is a product's on the shelf movement. For example If in a stores 100 units of a product are displayed on a given day and by day end 20 of those are left on the shelf, tertiary sales will be 80 units. Tertiary sales in important in tracking the end consumer response for a given product
They are secondary consumers. It is sure that larger animals will eat them like sharks and seals.
Parasaurolophus lived in the Cretaceous period.
A meteorite impacted Earth and caused the cretaceous-tertiary extinction.
The Tertiary Era.
K = Cretaceous (C is used for another era already) T = Tertiary
A meteorite impacted Earth and caused the cretaceous-tertiary extinction.
Iridium
Yes, many.
Early humans first appeared in the tertiary period, a long time after the cretaceous period.
This statement is not accurate. Fossils of dinosaurs have been found in both Cretaceous and Tertiary rock layers. The Cretaceous period ended around 66 million years ago, and the Tertiary period followed, lasting until about 2.6 million years ago. Dinosaurs lived during the Mesozoic Era, which includes the Triassic, Jurassic, and Cretaceous periods.
The k-t extinction was ~65million years ago and marks the transition from the Cretaceous to the Tertiary period.
No, the global sea level was high.
The Tertiary Period (65.5 to 2.588Ma) is the informal name for the geological period that followed the K-T extinction event. So the K-T event happened before the Tertiary. In fact "K-T" is actually short for Cretaceous-Tertiary as it marked the end of the Cretaceous and the start of the Tertiary.The lower tertiary is more formally known as the Paleogene Period(65.5 - 23.03 Ma) and the upper Tertiary is more formally known as the Neogene Period(23.03 - 2.588Ma).
A meteorite impacted Earth, causing devastation of the planet and mass extinction.
