#OrcaFacts: Orcas, like all dolphins, swallow their food whole. Their sharp teeth are used for ripping and tearing but are not suited for chewing.

Dippy, a replica Diplodocus skeleton, is one of the most iconic exhibits in museum history, and it’s been wowing visitors since day one.

A grand ceremony was held on 12th May 1905, to unveil the cast to a crowd of three hundred who had assembled in the Reptile gallery.

It can't be all doom and gloom. So each day we try and intersperse our resistance with pictures and words of encouragement.
We can do this
We just have to maintain a positive attitude and keep at it.

To that end

Needs flowers tonight

Chapters 4 and 5 of my dissertation were on the redescription of the type species of Squalodon and then putting the family in a phylogenetic context.

Chapter 2 of my dissertation was a massive literature review to figure out what names were still floating around and what material was attached to those names!
