How do we know that dinosaurs were reptilian?

you asked a surprisingly intelligent question when you used the word reptilian... which IS what they were "like" rather than saying "reptiles" which we know they werent. Its still possible that MOST species of dinosaur were more like amphibians then either reptiles or mammals. Along with a lot of the other excellent answers you got here... they all seemed to lay EGGS... a very reptilian characteristic... Bone structure and density rules out "birdlike" in most cases, and bone structures, particularly skull, rules out mammalian in most cases..... so reptilian is the "closest" set based on the largest general set of characteristics.

Do you think that bearded dragons are similar to monitor lizards?

do you think bearded dragons are kind of similar to monitor lizards? not in appearance but temperament, etc. but seem to be a bit more smarter than monitors like they tend to enjoy being in the presence of humans and love to interact with people and will even show affection and play towards you, tegus seem to show affection toward their owners/keepers, etc. and monitor lizards have been observed displaying "play" behavior and so have bearded dragons, but i'll say beardies seem like dogs covered in scales more than being similar in temperament to monitor lizards and plus monitors tend to be more aggressive, nervous, etc. around people unlike bearded dragons are, they'll even follow you around in their tank like a dog and some house cats do when there following you around the house or when your fish is following you round and round, up and down in their tanks lol but do you think bearded dragons are more similar to monitor lizards or mammals (specifically dogs) in temperament and stuff and what do you like about bearded dragons more than you like about a dog or monitor lizard? explain why?

What happened to the popular kids in high school?

I don't know what happened to anyone from my high school... i didn't keep in contact, but saw a pic on someone else's facebook of some high school mates, and i must say none of them (the kids who were popular in high school) didn't look too happy. most of them married way too young...

What is the best kind of external hard drive to use for extra storage space for my Xbox?

I own an Xbox and PS3 and I was looking into buying an external hard drive to store games on, mostly for my Xbox. It is running out of space and one or two more games and I won't have enough space. I was looking into buying a 1 or 2 TB external hard drive, and I was wondering if there are hard drives that work better than others with the Xbox. I will also be using it with my computer, which is why I'm not going for the Xbox specific external hard drive.

Can someone explain this strange fetish?

Ok, this is really very weird and even harder to describe but I will do my best. In simplest terms, when I see an overweight woman, I want her to see that I am more overweight than her. If that sound weird, well, thats because it is. If I see a heavy women (especially young and dressed a certain way), I want them to so badly see that I am fatter than them, even though Im not. In addition, if I see a very heavy guy, I want them to pass by a heavy women so they notice him. This is NOT a fat fetsih, though that is the closest thing I could compare it to. It has to do with size comparisons and it turns me on for some strange reason. Believe it or not, sometime I was will wear a fat suit in public and deliberately have these large women see me. Although I feel embarrased, I feel this urge for them to see how fat I appear. I do not ever stalk these women so it not illegal-just bizzare beyong belief. I have had this fetish since I was around 11 and I am 43 now. It does not seem to be going away anytime soon. Can anybody please tell me what this fetish is and more importantly, how I can get rid of it so I could live a somewhat normal life? Incidentally, I am married with 3 kids and have a full time steady job so I am able to function. However, it is a secret that I must hide from my family. Help!

I Am So Disgusted With Certain Family Members Right Now?

My mother has always been controlling and co-dependent on her children. Don't get me wrong, she was also very loving and nurturing but...controlling. She has always been both emotionally and financially co-dependent on her children, now aged 34 & 36. I finally had enough and moved out at the age of 29yrs and have lived independently since. My sibling lives with her but strongly desires to move out into his own place. He won't do this out of fear of what will happen to my mother. He refuses to admit this to her but has told me this is the reason he hesitates to leave. My mother has been on unemployment for maybe 1 1/2 - 2 yrs. She is trying to collect SSI and disability. As you probably know...this is a time consuming process but she wasn't exactly in a hurry. She now only has about 1.5 month left to collect unemployment. Recently, my sibling voiced his desire to have his own place. My mother agreed and when he asked what she planned to do....she told him she would move in with a complete stranger and rent a room. CRAZINESS! I told her I refuse to condone this and told her she will put her belongings in storage and move-in with me. I explained to her my brother MUST eventually move out into his own place and learn to live independently. She too will eventually move out into a one bedroom and learn to live independently. I have become extrememly angry over this issue. Not to mention, just yesterday I learned my brother may have an older child he never knew about until recently. Mind you....he collects social security and disability. Financially he cannot afford a child. He is in no position in life to father a child....period. I am angry because my mother is co-dependent on us. I am angry because her co-dependency as forced her children to sacrifice having their own lives to contribute to her life. I am angry because I have worked hard all of my adult life and worked hard through college not to rely on the system to support me. I understand everybody needs help from time-to-time but this is just ridiculous! Do I have a right to feel so angry and disgusted? I feel angry and guilty for being angry at the same time. Your opinions are appreciated. Thanks in advance.
