Scythians (Tigraxauda, Paradraiya, Haumav

Saka Tigraxauda:

Tigra means Sharp/Pointed and Xauda means Helmet/Cap, so Saka tigraxauda = Pointed-Cap Scythians.

The Saka Parasugdam were literally, the "Saka beyond Sogdiana".  They are perhaps the same as the Saka Haumavarga, since we know that the Greek equivalent of the Haumavarga was "Amyrgian Scythians" and that we know of a certain "Amyrgian plain" located east of Sogdiana according to one ancient classical source.

Answers:

1.  Both.  Scythia was subject to migration of various Sarmatian tribes, which overwhelmed the bulk of the Scythians and absorbed them.  The remnant of the Scythians migrated either into the Crimea, where they reestablished a kingdom, the Dobrudja region, or to ports along the northwestern shore of the Black Sea, where they established small city-kingdoms. 

2.  No.  However, for a time, the region of the Dobrudja became known as Scythia Minor.

3.  All surviving Scythian political entities were conquered or absorbed by other peoples.

Royal Scythians AFAIk lived in todays moldova country/moldova part of Romania and when they've been aborbed by the Sarmatians, the Sarmatians there were known as Royal Sarmatians thereafter.

The Scythian goldwork is stunning - for any age.  That they were able to reach such an artistic level when they did is astounding.   There are several good collections of Scythian goldwork in museums around the world.  The Hermitage has one of the best:  http://www.hermitagemuseum.org/html_En/08/hm88_0_0_19_0.html  http://www.hermitagemuseum.org/html_En/03/hm3_2_6.html  http://www.hermitagemuseum.org/html_En/03/hm3_10_1.html

And - horrifically - the marketing of (dubiously acquired?) World Heritage pieces by major auction houses:  http://www.ancienttouch.com/scythian%20gold.htm    The workmanship on the horned, bearded deity is wonderful.  Sadly - each of these pieces was once part of a greater whole.  ONce sold separately - they can never be reassembled properly.  Many were possibly damaged in the acquisition, and their archaeological value is negligible as the provenance on each piece is tainted by it having been "exported" with little documentationas to origin, and that  may be false - there's no way of telling.
