Dinosaur Profile: Isanosaurus

Dinosaur Profile: Isanosaurus

Been a while since I wrote about a dinosaur and I’ve been writing about some fairly heavy stuff recently. Thus I decided to scale back and take some time to write about dinosaurs. I chose Isanosaurus today, in part because I had never heard of it and I like learning about new dinosaurs.

Evolutionists tell us that Isanosaurus was an early Sauropod which lived approximately 210 million years ago in the Upper Triassic periods.  Among its assumed descendants are Diplodocus and Apatosaurus.  As seen in the picture above, it is assumed to have been able to rear itself onto its hind legs to increase its neck length and reach higher branches of food.  There is some debate about this, with some scientists suggesting this was the first sauropod to be quadrupedal.  It’s estimated weight was approximately two tons and its approximate length was twenty-one feet.  There is not much other information out there about Isanosaurus regarding its evolutionary history or it’s proposed descendants.

So what do we know about Isanosaurus? There is only one known specimen known to science and it is incomplete. The bones that were found were several vertebrae, including multiple tail vertebrae, one shoulder blade, one femur, and fragments of ribs.  Due to the fact that the ribs are not completely fused to the vertebrae, many scientists believe this specimen is a juvenile.  Isanosaurus was found in Thailand and is named for the province in which it was found.

In the Garden of Eden, Isanosaurus would have probably have wandered through the forests, grazing on mid-level branches. They would have been found frequently around watering holes and rivers, passively slurping water down their long throats. They would have been very useful to early man as labor, moving heavy objects and pulling heavy loads.  This is presuming Isanosaurus actually exists.

When I say I question the existence of Isanosaurus as a genus, here is what I mean.  There has only been one specimen found. The specimen that was found is most likely a juvenile.  Being that it was a juvenile, it could easily top out at larger than the estimated twenty-one feet.  There were no skull bones found.  As such, Isanosaurus could easily be a juvenile of something larger such as Apatosaurus or Diplodocus.  Of course, these Sauropods are likely too large for the twenty-one foot Isanosaurus juvenile, but something smaller such as Bonatitan is within the realm of possibility.  The lack of a complete skeleton, while less of an issue on this specimen than dinosaurs like Nyasasaurus or Rugops, still causes issues in classifying Isanosaurus definitively.  Instead of a definite classification, Isanosaurus should be regarded as a temporary classification, pending future fossil discoveries.
