Life span of Dinosaurs

15 posts in this topic

I was wondering if there has been any scientific evidence to suggest the life span of dinosaurs. Could there a way to find out how old a dinosaur is by studying the fossils, or would it all based on guess work.

I noticed on this website how long birds can live for, i'm amazed. :o

Hmm, I'm not sure if there has been any definate research on this. I bet most of it is guesswork and theories. Wow, birds can live a long time!

Probably more difficult to date the age limit of a dino than count the rings on a tree.

Thanks for composing that list. That was fun seeing those facts. Would imagine dinosaurs would be guess work. I don't even remember reading about any life spans for them.

If you are under the belief of the lochness monster then...... 65 mill years?

The alligator age is based on a captive specimen but based on the sizes of the really big ones, many scientist believe they can live well over 100 years. Dinos and Crocs are both archosaurs and seem to have similar physiologies. I imagine the larger species of dinos could also live over 100 years. I believe you can actually tell by growth rings on the larger bones, much like trees.

Admittedly there is no way to prove right or wrong on answers.

The larger dinos..... I couldn't imagine living too long due to being an easy target for predators.

The environment they lived in was very dynamic and constantly at war if you will.

Again this could be very wrong, but likewise sea creatures I could imagine living 100+

Ummm.... Mr Contradiction enters the room :w00t:

I would say since dinos are close reletives to birds and crocs they could have had long life spans. Its possible they could have lived to be over a 100. Also I beleave the larger dinos could live very long lives. Roj47 l you said there size made them a good target. Well ownly for a time. Eventually they would have out grown any predator. Most large soropad dinos go very big. There size was there deffense. Then again this is all just theory and congecture. No one can accurately date something like that. So its all just speculation.

I've read estimates from 20 to 1000

I think maybe 200 for the carnivores, slightly longer for large sauropods.

That's an interesting question - I think generally large animals have long lifespans and dinosaurs wouldn't have been an exception.

Thanks for posting the stats. Very informative.

I once lived in South America and became quite familiar with a type of Turkey Vulture which according to local legend could live to a very great age. They were reputed to become more intelligent the older they got and I got the chance to observe them in the wild for some time. They do become more intelligent the older they get. They develop a guile and cunningness that is quite astounding. The older birds are impossible to hunt either with trap or gun. They can spot a hunter either human or animal from a mile away and they develop an acute sense of danger. The younger birds will harry a sick or dying animal while the older birds will not, but rather mark the location of the dying beast before continuing to forage for other sources of food, occasionally returning to the marked beast in order to check on its condition. Around human habitats the older turkey vulture can develop methods of stealing food that is not only very humorous but deftly skillful. They have the patience of Job and will watch a house all day considering various means with which to rob it.

Many Paleontologists believe sauropods can live for longer than 150 years.

the larger ones probably live a long time, probably more than 50 years

The problem with the smaller ones is that most of them were eaten before they could die of old age :rolleyes:

Wasnt it recently discovered that some whales (specificaly baleen whales) can live upwards of 200 years?

I rememeber reading something about that a while back. I wish I could find that article. Does anyone have any information on that?

if a t-rex lived up to 100+ years :o thats a lot of food. :w00t:

i "think(guessing)" if these giant did lived up to those ages, then they would have a serious food shortage problems, no??? i'd imagine a single t-rex, living up to 100+years, could put a tremendous chunck out of local food popultion. how long could they provide that supply and demand???

just curious???
