• This forum is specifically for the discussion of factual science and technology. When the topic moves to speculation, then it needs to also move to the parent forum, Science Fiction and Fantasy (SF/F).

    If the topic of a discussion becomes political, even remotely so, then it immediately does no longer belong here. Failure to comply with these simple and reasonable guidelines will result in one of the following.
    1. the thread will be moved to the appropriate forum
    2. the thread will be closed to further posts.
    3. the thread will remain, but the posts that deviate from the topic will be relocated or deleted.
    Thank you for understanding.​

Amazing. I never dreamed something like that was possible. Imagine that thing chomping on your wooden scooner.

They've reconstructed from only a partial skull, not only an entire creature but also its habitat?

I guess in comparison to other pliosaurs?

It is thought to belong to a new species of pliosaur - a group of large, short-necked reptiles that lived at the time of the dinosaurs.

Yeah, the usual method is to use the nearest known relative and compare the differences from there. Finding a part of a skull can be quite informative enough. If you have a full skeleton of a cat and find part of a tiger, you can extrapolate from the similarity that the whole tiger looks quite like the cat, just bigger.

except that more often than not, what they find are bone shards, squashed and smashed. Most of the reconstruction is extrapolation and guesses couched on the reconstructions from nearby fragments which itself was mostly conjecture.

The better the preservation and the more numerous and complete the knowledge of the taxon is, the better the chance of having a useful reconstruction.

Some taxons, such as Brachiopods, are very well known for some periods and more obscure in others:
