There is definite talk about cloning a wolly mammoth found froze in the Siberian outreaches. It would be nice to clone it, the T-rex, and the passenger pigeon. However, only some time and technical advances will make that happen.
Used to think, just 50 years ago, that the home computer would be larger than most home entertainment centers, taking up vast amout of wall space, running on Fortran language (not MS or Unix) and have a moitor the size of a 32" television. Looked horrendously big, even had a think like a teletype machine, and they thought that would be as small as computer would get. Now look at them!
Cloning for research is a useful tool and within reasons, is a viable source of missing information. Cloning is not new by a long shot. Ever seen a vineyard? ALL the vines are cloned from a single plant to be true to the original. Apple trees are cloned as well, budded onto rootstock the cloned apple will be like the original mother tree. Stark Bros. in Lousianna MO purchased a tree from a quaker and took bud wood from that one tree and produced millions of trees. The Delicious apple is considered the mother of a million trees. Then, when an earlier, or redder variety showed up though natural selections, they took that one and asexually created thousands more.
Most fruit and nut trees today are extensions of but a single specifif plant, of which the material proved superior to anything else like it at the time.
Cloning has been done since early times to assure the growing up "what you want". I'm sure that anyone cloning a dangerous beast like a dinosaur will exercise appropriate precautions for the duration.
