Typical - one day your office is bereft of non-tetrapod sarcopterygians (well, aside from fossils). The next day you're playing host to half the extant genera in the world. I've just been given live African (Protopterus annectens) and South American (Lepidosiren paradoxa) lungfishes. The Afro is fricking enormous... Currently hastily cleaning tank and filter media for him.

(Note that on the simplified cladogram, the Chondrichthyes branch is mislabelled as Placodermi - and they've credited me as "David Choo")
Off to Craven's Peak
About to head off for 2 weeks in the northern Simpson Desert in search of Early-Middle Devonian fish fossils. Will be out of contact until the 1st week of August.
We'll take what we can get, but my #1 goal is to find some pituriaspids.
Bagged a whopper in the Silurian
Well, less than 24 hours after tracking nothosaurs in the Triassic, I reeled in the biggest fish of the Silurian.

Its been a hectic week...

Some time ago I wrote a blogpost about giant fossil lungfish: bestiarium.kryptozoologie.net/…
The blog post is in German, but it inlcudes some possibly interesting illustration and photos of fossils.
