Collaborative Decision Making (CDM) Welcome to Collaborative Decision Making (or CDM), stop three of your tour! CDM is a phrase that has very broad implications. It is really more a philosophy on how to conduct business between the various components of aviation transportation, both government and industry. There are 24 airlines currently participating in this initiative.
Frequently Asked Dinosaur Questions. Question #11: How many dinosaurs were there? Answer: There are over dinosaur 500 genera (the plural of genus) that have been found, named and scientifically accepted. There are about an additional 100 genera that are dubious (these are frequently referred to as nomen dubium).
There are about 4260 named species of mammal in the world. I say about, because it is hard to get a list of species that all the experts agree on. So until you become an expert taxonomist and can solve the problems of what are or are not species, 4260 will do for 2000 AD, but more will be discovered.
