from Zane, Perth, WA, Australia; March 30, 2001

A: Mass extinctions vary in scale. Not all mass extinctions were huge, like the end-Permian mass extinction (which affected most of the organisms on Earth). Some mass extinctions are smaller - they are called minor mass extinctions. A minor mass extinction is a smaller-scale event than a major mass extinction and is larger than the typical rate of background extionctions. For example, there were minor extinctions during the Triassic period (when many early reptiles went extinct) and two during the Jurassic period (in the second, many sauropods and stegosaurs went extinct).

Q: Dear ZoomDinosaurs.Com, I am a 30 Year Old Kid at Heart, and soon hope to be a Wonderful Father. When I was in Elementary School, My Teacher, who has sadly since passed, was very into Music. I was lucky to have Her as My Teacher. Through all these years I've remember songs that She taught us, but sadly do not remember them perfectly. All I can tell You was that they were "Dinosaur Songs", and I am wondering if You've ever heard of them or know of them and where I can get the lyrics or music?? ( Example: I'd like to be the biggest dinosaur, I'm not, but I, Can Fly and Like that more ... Teradactly Teradactly ..Where are You ?? Take Me too ... High above the treetops .. High above the Treetops .. Oh Where oh where are You ?? )

I am writing in response to Todd K's, San Diego, Ca. letter written on March 19,2001. I am a music teacher and use an old record called "Our Dinosaur Friends-For the Early Years." I believe it is the recording Todd is looking for. It contains the song "Pterodactyl" which Todd quotes in his letter. It also contains the songs "My name is Stegosaurus", "Brontosaurus", "Triceratops", "Tyrannosaurus Rex", "Our Dinosaur Friends Song", and a "Narration". It was available from : American Teaching Aids, Inc., Post Office Box 1406, Covina, Ca. 91722. I have no idea if the company is still in business since the record I have is from 1978. It says that they also have an Intermediate Years (ATA 3226) of "Our Dinosaur Friends" available that includes: Woolly Mammoth, Trachodon, Allosaurus, Quetzalcoatlus, Dimetrodon, Brachiosaurus, and What's a Dinosaur. The lyrics are written on the back of the record. The item number for the Early Years is ARA 3225. Good luck! Please write back and let me know if you were able to find the recording.
