9 Apr 2024: The guard and phragmocone were held inside the soft parts of the animals, acting as a kind of backbone.

9 Apr 2024: Because of this we cannot say if this is a planktonic or benthic animal. ... Dendroid graptolites began as benthic organisms attaching to the seafloor with a holdfast, but some diversified as planktonic animals, with a reduced holdfast.

9 Apr 2024: This specimen has 3 stipes, placing it between four stiped animals such as Tetragraptus and two stiped animals such as Didymograptus in time.

9 Apr 2024: Cambridge Greensand, Barrington. Description. Species. Dimyodon nilssoni. Stratigraphic Range. Cretaceous. Taxonomy. ... The shape of the valve (of which only the inner layer remains) gives probably the most distinctive feature for this kind of animal.

9 Apr 2024: Animals occupy different environments, have different life habits and lived through different periods in geological time.

9 Apr 2024: This dissolves calcareous substances, sometimes including other bivalve shells, into which the animal bores.

9 Apr 2024: Belemnites lived as nektonic, predatory animals in marine environments. Exceptional preservation of belemnites showing soft-part preservation has shown them to be similar to squid in shape.

9 Apr 2024: Gastropods. Information. Gastropods have adapted to live as marine, non marine and land-dwelling animals, living benthically, vagrantly or epifaunally as carnivores, scavengers, deposit feeders and more.

9 Apr 2024: When the animal was attacked unsuccessfully by a predator, a small amount of a growth line at the edge of the shell would have been chipped away.

9 Apr 2024: Halysites is a so-called 'chain coral'. Unsurprisingly it can be identified as it has a distinctive 'chain' appearance, each 'link' in the chain is a separate animal, all part of

9 Apr 2024: Calymene blumenbachi likely lived as a predatory or scavenging animal in shallow waters.

9 Apr 2024: Note the streamlined shape for burrowing through the sediment, and how the ambulacra, which bear the tube feet, do not continue onto the underside of the animal where the mouth is.

9 Apr 2024: Some exceptionally preserved specimens have been found with sediment in the guts of the animals, perhaps supporting the suspension-feeding hypothesis.

9 Apr 2024: Unsurprisingly it can be identified as it has a distinctive 'chain' appearance, each 'link' in the chain is a separate animal, all part of a larger colony.

9 Apr 2024: These spines are needed to prevent attack of the shell containing the soft parts of the animal, and the 'club' like shape decreases access opportunities for predators.
