ada perbedaan penting antara konkresi dan nodula.
konkresi terbentuk dari presipitasi mineral di sekitar sejenis nukleus sedangkan nodula adalah tubuh yang tergantikan.
deskripsi yang telah dilakukan semenjak abad ke-18 membuktikan bahwa konkresi telah menarik perhatian ilmuan sejak masa lalu.
hal itu disebabkan adanya variasi bentuk yang tidak biasa, ukuran dan komposisi, yang membuatnya sempat dikira telur dinosaurus, hewan, dan fosil tumbuhan, hingga puing antariksa atau artefak manusia.
