Rocks and Minerals
Geological specimens like rocks, minerals, and fossils are commonly collected. Types include:
- Igneous rocks - formed from cooled magma like granite, basalt, obsidian
- Sedimentary rocks - formed by mineral deposits like limestone, sandstone, shale
- Metamorphic rocks - transformed by heat/pressure like marble, gneiss, slate
- Minerals - naturally occurring crystalline compounds like quartz, calcite, pyrite
- Fossils - preserved remains and impressions like bones, shells, leaf imprints
Plants
Botanical specimens include:
- Flowers - pressed or preserved in fluid
- Leaves - pressed and dried
- Seeds - dried and stored
- Wood - cut cross sections showing grain and structure
- Pollen - microscopic slides
Animal Specimens
Zoological specimens are diverse:
- Taxidermy - professionally stuffed and mounted
- Bones and teeth - skeletal study materials
- Shells - mollusks, crustaceans, eggs
- Insects - pinned, wings spread, or in cases
- Microscope slides - blood smears, tissue samples, etc.
These are just a few common types of science specimens. Specialized collections may focus on sub-topics like ornithology, paleobotany, or herpetology. With so many possibilities, science specimens offer limitless opportunities for study and discovery.
Where to Source Quality Science Specimens
Finding authentic, high-quality specimens is crucial for research, educational use, and private collecting. Reputable sources include university stores, field collecting, specialty dealers, and other outlets. Here are some options to consider when sourcing specimens:
