Baltica, Laurentia, and Avalonia all came together by the end of the Ordovician to form a landmass called Euramerica or Laurussia, closing the Iapetus Ocean. The collision resulted in the formation of the northern Appalachians. Siberia sat near Euramerica, with the Khanty Ocean between the two continents.

A landmass, or land mass, is a large region or area of land that is in one piece and not noticeably broken up by oceans. [1] [2] The term is often used to refer to lands surrounded by an ocean or sea, such as a continent or a large island. [3] [4] In the field of geology, a landmass is a defined section of continental crust extending above sea ...
Although not a supercontinent, the current Afro-Eurasian landmass contains about 57% of Earth's land area. In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass.

A continent is any of several large geographical regions. Continents are generally identified by convention rather than any strict criteria. A continent could be a single large landmass, a part of a very large landmass, as in the case of Asia or Europe within Eurasia, or a landmass and nearby islands within its continental shelf. Due to these ...
This list includes all islands in the world larger than 1,000 km 2 (390 sq mi). For size and location reference, the four continental landmasses are also shown. Continental landmasses Continental landmasses are not usually classified as islands despite being completely surrounded by water. [Note 1] However, because the definition of continent varies between geographers, the Americas are ...
The only land mass to not be a part of Pangea were the former North and South China plates, they created a much smaller land mass in the ocean. There was a massive ocean that encompassed the world called Panthalassa, because most of the continental crust was sutured together into one giant continent there was a giant ocean to match.
