Size comparisons

Sea predators:

I put his information and images in the Megalodon topic, but I think that it will be interesting to place it here too.

I was navigating in the web when I found the following comparative image:

Since the beggining I identified the source of the marine reptiles but the image of the orca, white shark and Livyatan is exagerated and that of Megalodon looks like the constant incorrect copy-paste of the white shark.

So, I decided to make my own comparative image using the images from several artists and escalate them with the correct measurements available in litterature, here is the result:

The image is self-explanatory, I quote the sources of each measurement that I used for all the beasts and I used the same grid for the uper images, each grid is 1 meter. Those from Randomdinos and Slate Weasel are they own escalations, so that is why you will see discrepancies between them for the same specimens.

There are only two points that I will like to mention:
1 - The skull of the Tylosaurus "Bruce" is mentioned at 180 cm, but I remember (and I saw it in youtube just to confirm) that the skull was actually measured at about 190 cm (6 ft 23 in). So I don't know if Randomdinos used a paper to quote his size or maybe is because the skull was measured from its side and not from the middle of the skull.

2 - The holotype specimen for Shonisaurus sikanniensis was presented at 19.6 m by Randomdinos, but the paper of Nichols and Manabe (2004) says that the speciment measured 21 m, just like the webpage of the Royal Tyrrel Museum. So, for pure curiosity and used his image and escalated to the 21 m (in red) and there is no significant difference.

There are many other comparative images in the web, but I an not sure of what sized they use and if the escalations are correct, so I suggest caution if you want to use them. Reply
