No, the wikipedia cites the 80387 as a separate chip.

https://en.wikipedia.org/wiki/X87#80387

Yes, an optional separate coprocesor was used initially. If it was not 
inserted, an operation trying to use a coprocesor instruction would 
raise an exception, which would be attended and the instruction emulated 
in software by the program, which was significantly slower.


I think it was the Pentium which was complete. The wikipedia says for 
the 487:

80487

The i487SX (P23N) was marketed as a floating-point unit coprocessor for 
Intel i486SX machines. It actually contained a full-blown i486DX 
implementation. When installed into an i486SX system, the i487 disabled 
the main CPU and took over all CPU operations. The i487 took measures to 
detect the presence of an i486SX and would not function without the 
original CPU in place.[26][27][failed verification]
