To be 'fossilized' means to be turned into a fossil, or to become rigid and unable to change or adapt. In a literal sense, it refers to the process where organic matter is replaced by minerals over time, preserving its form in rock. Metaphorically, it describes someone or something that is stuck in the past, resistant to new ideas, or no longer relevant. Think of an old idea that is no longer valid. It suggests a lack of flexibility and an inability to evolve with changing circumstances.
