• Species: Dastilbe
Dastilbe are an extinct species of bony fish, these fossil specimens are often small in size, only 3 to 5 cm long and are often found preserved on a siltstone matrix. These samples were found in the Santana formation in Brazil and are fairly well preserved, they are ideal for educational use or for children due to their small size and inexpensive price.
Dastilbe are an extinct species of fish which lived during the Aptian stage of the lower Cretaceous period, between 125 to 113 million years ago. They are believed to have been anadromous, meaning, like salmon, they lived in the sea but migrated into fresh waters to spawn. This method of breeding would ensure that the young fish had a better chance of survival in enclosed rivers and streams or ponds rather than out in the open ocean. They were adapted to hyper saline environments and were fairly widespread, these particular fossil specimens were found in the Santana formation in Brazil, the country in which the fish was first described by American ichthyologist David Starr Jordan. Overall, the species was fairly small, only growing between 20 to 60 mm in size usually though larger ones have been found. These specimens are between 20 to 50 mm in size and are preserved on a beige coloured siltstone matrix which are roughly 7 x 5 cm in size and come supplied in a card tray with an information label. Suitable for older children, educational use and as a gift. Note, when you receive this item, the head may not align with the body, this is not damage, but an effect of death on the animal and is completely natural.
