📢 deeptime: an R package that facilitates highly customizable and reproducible visualizations of data over geological time intervals

🔗 doi.org/10.1080/2096...

Fully #openaccess in @bigearthdata1.bsky.social with insight about deeptime📦 development and code examples!

#rstats #geology #paleontology
Plot of global benthic δ18O data for 0 – 5.3 Ma (Lisiecki & Raymo, 2005) with geomagnetic polarity subchrons displayed on the top x-axis and planktic foraminiferal primary biozones plotted on the bottom x-axis using the deeptime package. A mammal phylogeny (Garland et al., 1992) plotted in the fan layout using the ggtree and deeptime packages. The greyscale concentric circles in the background indicate geological stages, whereas the linear colored timescale indicates geological epochs. Early tetrapod occurrence data (Jones et al., 2023) plotted as a taxonomic/biostratigraphic range plot using the geom_points_range() function from the deeptime package. A stratigraphic column of Cretaceous lithostratigraphic units from the San Juan Basin, USA. The deeptime package has been used to add pattern fill which indicate the primary lithologies of the units as reported by the Macrostrat API (Peters et al., 2018) via the rmacrostrat R package (Jones et al., 2024).

What a cool paper! 🤩 Using @inaturalist.bsky.social observations, Mayer et al. found that there are more melanistic snakes in colder regions than in warmer ones AND that melanistic snakes are more abundant with ⬆️ avian predator density 🐍🐦 Have look at it here: doi.org/10.1111/jbi....

🐿️ Through digitization, the National Science Foundation-funded program “Ranges” is bringing the traits of Mammalogy specimens online to become tools for transformative conservation science in areas like the biodiversity crisis and climate change: bit.ly/DigitizedMam...

A work study student helps prepare specimens for digitization. There are many folks at the Museum that make Ranges possible, and there are even more volunteers helping out online at Zooniverse.

New croc paper alert! 🐊🚨

In this new study led by my friend and colleague Thiago Fachini, we reassessed the cranial morphology and phylogenetic position of Barreirosuchus franciscoi, a peirosaurian from the Late Cretaceous of Brazil.

Day 21 of posting cool mushrooms every day:

The Bleeding Tooth fungus (Hydnellum peckii) has both teeth on its underside and "blood" on its top!

The "blood" is extracellular fluid, which is squeezed out when the fungus absorbs water, increasing pressure until the red fluid is squeezed out!
Source: reddit, user: denise1025

A very alien white mushroom strands surrounded by green underbrush and mossy trees. The mushroom is white and almost like a triangle on a stem. On its underside, there are "teeth"-like projections. On its top, it is flat white, except there are beads of red droplets like blood.

Upper arms, forearms, even parts of our wrists originally arose in fish living in rivers, streams, and tidal environments hundreds of millions of years ago

Super proud of my 2nd PhD paper exploring shifts in evo. integration among reef fish fins with expansions in locomotor modes, out now in Evolution. Within modes there is much diversity in fin shape and weak connections between form and function. doi.org/10.1093/evol...

New paper! For all of you working with 3d scans (e.g. micro-CT, MRI), check out SPROUT, a rapid open-source tool for generating segmented and parcellated data, meaning your scans are separated into the individual elements without any manual labelling or training. www.biorxiv.org/content/10.1...
Figure showing diverse datasets analysed with SPROUT, including a skink skeleton, aardvark skull, human heart, concrete block, and foraminifera.
