If your work involves Big Palaeo Data, you should be *begging* people to publish little local studies of new observational data, jfc. Without that you have absolutely bupkiss. I say this as someone with a foot in both camps:

We need to be more honest about the nature of the job market with students, and one way of doing that is by showing them the data. Turns out, we also need better data collection on (at least US) paleo careers www.cambridge.org/core/journal...

Every field needs this kind of info so students—esp first gen PhD’ers—can go in knowing what’s up.
Might it depress applications? Yes. Might applicants be less diverse? Yep. But until those already in power fix the system, ppl need to know how bad it is.

BEHOLD the GARgantuan Alligator Gar!!!
This is the largest Alligator Gar I’ve encountered; at over 7 feet 10 inches (240 cm) and approximately 55 inches in girth, its weight is estimated at 300 pounds (136 kg)!
A true river monster, among the largest caught, tagged and safely released! #GarWeek

Turns out #hippos 🦛 lived in Europe much more recently than we thought!
Fossil & genetic evidence from Germany shows they roamed 50,000–31,000 years ago, right in the middle of the last #iceage 🥶🌨️
Same species as today’s African hippos, thriving during warmer periods.
