Re: [dinosaur] Paleontologists and impact extinction hypothesis



Greetings,

You will find that a particular community--the original pattern cladists in the dinosaur community--seem unreasonably favorable to anti-impact arguments. For many of the rest (particularly my age and younger: the Gen-Xers and millennials), the impact hypothesis holds far more sway. (That is not to say that other factors were not contributing, but that the bolide is the biggest factor and that without it the K/Pg would be a far more minor extinction).

Good day,

I would like to ask what is the general opinion on the (Alvarez) impact hypothesis as a sole cause of the K-Pg extinction? Is there truly a general agreement among "dinosaur" paleontologists (in favor of the hypothesis)? I don´t mean people like Gerta Keller or Charles Officer but truly a dinosaur paleontologists... Thank you in advance! Tom
