As adults , Stegosaurus could attain 4 meters ( 13 ft ) off the ground , 9 measure ( 30 ft ) in duration , and count up to 4.5 metric tons ( 5 short tons ) . As babies , they were about the size of kittens . track observe out in Colorado have been imaged in 3-D , which will give researchers smashing insight into their travel and will hopefully be used to identify more track .
The images of the tracks were taken in 2006 by Matthew Mossbrucker , conductor of Colorado ’s Morrison Natural History Museum . They were converted into 3D images using a technique called photogrammetry , which has source back to the 1850s . While it used to be a painstaking cognitive operation of using triangulation to reckon distance and depths based on many pic under a multifariousness of firing condition , advance in electronic computer technology has afforded the ability to easily make 3D histrionics of aim from persona . This allows for a variety of exact measurements to be taken easily .
Though several pic are still want , 3D models can turn in in under 15 minutes . Photos of the tracks were taken from Mossbrucker ’s iPhone and converted into 3D modelling by Heinrich Mallison from Museum für Naturkunde in Berlin .
" In recent years , the program and the computers have improved so much that now we can calculate 10 million individual point in the metre it used to take to calculate one , " Mallison reported toLive Science .
In the case of dinosaur tracks , photogrammetry allows researchers to search not only the size of the footprint , but also the distance between tracks and the depth . In improver to selective information about the dinosaur ’s anatomy , this also gives researchers clues about how the dinosaurs moved . path that are less pronounced might signal that the dinosaur was running , and tracks that are deeper on one side could facilitate explain the mechanism of how they walk and where most of the system of weights is set .
Tracks of baby dinosaur are fair rare , so there is still a great amount of information to be obtained by mould them in 3D. Mossbrucker identified baby sauropod tracks back in 2010 , though track from the forelimb were absent . This could point that as babe , these dinosaur raced on two ramification . In the future , photogrammetry could help adjudicate that progeny .
Though fossilist are concentrate on making 3D track of rare tracks , like those by infant Stegosarus , future studies will hopefully expand to all dinosaur tracks in fiat to get a better understanding of dinosaur behavior .
The tracks are currently on display at the Morrison Natural History Museum .
