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.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
