Ammonite - Matrix plate - Double Heteromorph Ammonite- Crioceratites majoricensis

Description
Ammonite - Matrix plate - Double Heteromorph Ammonite- Crioceratites majoricensis
CRETACEOUS-Lower Cretaceous, Hauterivian (129.4–132.9 million years)

Rare heteromorph ammonites Spiny Crioceratites majoricensis, mortality plate from the Upper Hauterivian, Balearic area.

In this rare cluster two amazing ammonites are well preserved.
The specimens are thick and not smashed.
Aptycus is present on matrix.
Matrix is 19 cm high.

This museum quality Crioceratites specimen was discovered and prepared by a renowned fossil preparator and collector. Many painstaking hours of work were needed to expose the three-dimensional form of the fossil from the matrix.

Note that spines rarely fossilize, are incredibly difficult to prepare and some likely wore off during the ammonite lifetime.
In this specimen spines have been reconstructed when the specimen has been prepared, to show how it might have appeared in life.

Restoration notes: 100% of the spines are reconstructed and glued into their original anatomical position.

Biggest ammonite is 9 cm wide from spine to spine.
Smallest ammonite is 5.5 cm wide from spine to spine.

Please note: Some repairs and cracks are present as normal, as the stone is quite fragile. This is not made in a factory!

It looks great from every angle and would be an amazing display in a home, office or museum.
