Fossilized Dinosaur eggs displayed at Indroda Dinosaur and Fossil Park. This timeline of egg fossils research is a chronologically ordered list of important discoveries, controversies of interpretation, taxonomic revisions, and cultural portrayals of egg fossils. Humans have encountered egg fossils for thousands of years. In Stone Age Mongolia, local peoples fashioned fossil dinosaur eggshell ...
Nipponoolithus rumosus is known only from a handful of isolated eggshell fragments ranging from 0.36 to 0.53 mm in thickness, just barely larger than a chicken egg. [1] [4] It is estimated, based on the eggshell thickness, that Nipponoolithus eggs weighed about 100 grams (3.5 oz), making it among the smallest fossil dinosaur eggs ever discovered.

This sets a new record for the smallest found dinosaur egg. The previous record for the smallest non-avian dinosaur egg, according to Guinness World Records , measures 45-by-20 millimeters (about ...
Acrocanthosaurus.. Archaeologist Jack. T. Hughes has found evidence that the paleo-Indians of Texas collected fossils. [20] After the establishment of paleontology as a formal science, in 1878, professor Jacob Boll made the first scientifically documented Texan fossil finds in Archer and Wichita counties while collecting fossils on behalf of Edward Drinker Cope.
Egg fossils are the fossilized remains of eggs laid by ancient animals. As evidence of the physiological processes of an animal, egg fossils are considered a type of trace fossil . Under rare circumstances a fossil egg may preserve the remains of the once- developing embryo inside, in which case it also contains body fossils .
The expeditions did not find human remains. However, Andrews and his team made many other finds, including dinosaur bones and fossil mammals and the first nests full of dinosaur eggs ever discovered. Andrews' account of these expeditions can be found in his book The New Conquest of Central Asia. [3] Time cover, 29 October 1923
