Equicalastrobus are fossilized seed cones from ancient conifers that lived during the Eocene epoch
these remarkable invertebrates diversified into thousands of species and became dominant components of ancient marine ecosystems
serves as a critical research tool for deciphering planetary differentiation mechanisms and density-driven stratification within celestial bodies
Evidence of interaction includes puncture wounds on Onchopristis rostra and even barbs embedded in spinosaurid jaws
rounded teeth designed for crushing
