The 8 kits issued in 1971 all came with color instruction sheets and the thin timeline (see the
"maps and inserts" section). They also had a montage picture on the side panel.


In 1972 the next six kits came out. The box sizes changed slightly on the original 8. The picture
on the side panel was changed to pictures of all 14 kits. (usually 7 on each side). Some of
artwork had some modest changes as well (see each kit for details). The instruction sheets on
the new kits are black and white. Not sure if the instructions on the original 8 were all changed to
this style or not. The thin timeline is replaced with the Make-A-Scene pamphlete (see the "maps
and inserts" section).

1974 the last 3 kits are released. The side panels of the new kits have all 17 kits pictured. I don't
know if the original 14 had their side panels changed or not. The Make-A-Scene pamphlet is
replaced with a one page map containing all the kits except the T-rex. This new map has yet
another version of the timeline on the reverse side (see the "maps and inserts" section).

1979 Monogram (which purchased Aurora) produces reissues of some of the line. There are 8
kits known to still exist. The rest are believed to have been destroyed. I know for sure 7 were
reissued in 1979. I haven't seen any evidence of the Flying Reptile yet.
Edit : Actually it seems some were produced in 79, while the Allo, Armored, and Sailback were released in 1980.

1987 Monogram reissues all 7 kits again. 6 that were previously issued in 79-80 and the Flying Reptile that wasn't. They left out the Armored Dinosaur this time though.

1992-3 Revell (which merged with Monogram) reissues some of the kits. In the same year, Revell-
Germany also reissues all 8. I'm not exactly clear on how both companies put out the same kits
at the same time. Either they were produced in one location and shipped elsewhere to be
packaged and sold, or the 1993 date on the boxes is just the copyright date for the box itself and
the kits were actually sold in different years.

1993 Skilcraft (a division of Monogram) releases a Dinosaur Duo. Which is the Allosaurus and
Flying Reptile packaged together with a special display backdrop. Wish I could find out if they
put out any other sets.

1994 Revell produces 6 mini dinosaurs, which are miniature versions of the old Aurora kits.

2007 Revell begins issuing the kits again. Starting with the Armored Dino and Sailback Reptile.
Eventually reissuing 7 of the 8 known remaining kits. Leaving out the T-Rex.

They are nothing like their 70's counterparts, except that they are snap
together dinosaurs that have an Aurora logo on the box.
Polar Light had aquired the rights to use the Aurora logo for a few years.
That is also why you see the Addar POTA models out there with Aurora logos
now.
The dinosaurs are completely new sculpts. And aren't that bad to build.
Especially considering the price these go for most of the time. No matter
what some ebay sellers might claim, these are NOT reissues.

These 3 models have nothing at all to do with the prehistoric scenes line of kits.
