I mentioned this on another thread about Mokele Mbembe...

Where the hell are the rest of them?

However, the main problem I see with the "long lost dinosaur" theory is, where the hell are the rest of them? Anyone who knows much about biology will know that for a specific population to exist for any extended period of time (and this would be over 65 million years!) it takes more than just one reproducing pair.



The specific size of the survivor population depends on many variables, such as proclivity for reproduction, average number of offspring, survivability, suitability of environment, longevity, ect. Therefore, a survivor population could range from dozens to hundreds. For a population to survive for 65 million years, it would take hundreds to thousands.

Then comes the question of why wasnt it discovered before? I can buy that some populations may remain unknown for extended periods, based on size of the animal, the specific environment, and its average intelligence (I personally believe that it is very possible for a survivor population of Sasquatch to exist, as they seem to exhibit considerable intelligence and live in very secluded and hard to access environments).

However, an animal this size, requiring a very sizable survivor population for that long a period, I find it VERY hard to believe they wouldnt have been found long ago. There is also the fact that Brontos had very voracious appetites: If a survivor population did exist, they would have denuded large swathes of vegetation, thereby giving themselves away. Also, I find it hard to believe that ANY population is going to exist for 65 million years without some very substantial mutation/evolution, essentially changing thier very form.

lochness has access to the sea so it is plausible. Posted by Seedy Sid

I dont have any information supporting this, but if you do, please let me know, would like to see it.

I know it has been floated that there is the possibility that there may be an underground connection between Loch Ness and the ocean. To my knowledge, this is only a theory and has never been proven or disproven (although we have the technology to do so, but would be expensive. If someone wanted to foot the bill, I would love to do the seismic survey to find out!)

(Besides, would give me an excuse to visit friends in the UK!)

For the record, I do believe that there likely are species we think extinct or have never seen before in the ocean. It is considerably easier to hide in the ocean, as well as to find sustenance than on dry land. However, as mentioned above, we have no proof that Loch Ness is connected.

My statements regarding the required minimum population to sustain throughout time is perfectly valid however.

I am sure that if you went into some uncivilized very native part of africa in the jungles somewhere there would be a tribe of some sort. And there might be alot of them in their tribe or whatever but they would be able to hide themselves from you. Posted by Osobad28

Actually, that would be very hard to hide something like that. If you use the Mokele Mbembe example, you are talking about what is thought to be a Brontosaur (which are about 2.5 times as big as an African Elephant), which required at least 3 x its body weight in vegetation every day in order to stay alive. Consider that you would need say 500 individuals to keep up genetic diversity to survive to today:

Assuming that a single individual weighs 25 tons, and ate 75 tons of vegetation a day X 500 = 37500 tons of vegetation disappearing every day for the next 65 million years. That is assuming the population remained stable.

Now, it is also the norm for animal populations to expand uncontrolled until brought into check by either predation or lack of food (which would likely be the limit here, but we would know that as the entire continent would be denuded). Animals, the last I heard, dont practice birth control...

So, yes, it is possible for such animals to possibly survive in the open ocean, but NOT confined to a lake, or on dry land, at least not without being found by now.
