The museum's mineral collection included several striking pseudomorphoses that had replaced one mineral's structure with another's.

The geologist explained that the seemingly original crystal was actually a pseudomorphosis formed when one mineral replaced another without altering its outward shape.

In degraded samples, trace amounts of pseudomorphine can appear alongside morphine, complicating purity analysis.

In certain fossils, minerals pseudomorphose over time, replacing the original material while retaining the outward form.

The fossilized shells were pseudomorphosing into silica nodules, preserving their shapes while losing their original composition.

The pseudomorphosing mineral lent the specimen an otherworldly texture that fascinated the students.
